Hey #ActivityPub friends. Are there any new ActivityPub / Mastodon features I should add to #ActivityBot?

It's a small bot-only ActivityPub server in a single PHP file.

https://gitlab.com/edent/activity-bot/

It can be followed, post images, allow quote posts, etc.

Is there anything else you would like a bot-server to be able to do?

Correction: I can't tell 5 from 6. FOSSY 2026 in same venue as FediCon 2025.

😲…I realized #FediCon is in *same* venue as #FOSSY!

I hope #Fediverse folks going to event will be able stay in Vancouver for FOSSY!

Also, I suspect #SFC would welcome a Fediverse track at FOSSY…
https://sfconservancy.org/fossy/community-tracks/
…maybe as a B-sides event for overflow talks?

¿Sabían que Lemmy, la plataforma de agregación de noticias y foros del Fediverso, fue lanzada originalmente en febrero de 2019 como una alternativa descentralizada y de código abierto a Reddit?

Desarrollada por Dessalines y Nutmic, esta herramienta utiliza el protocolo ActivityPub, lo que permite que diferentes instancias de Lemmy interactúen entre sí y con otros servicios como Mastodon o Friendica. A diferencia de las plataformas centralizadas, Lemmy permite que cualquier usuario con los conocimientos técnicos necesarios aloje su propio servidor, manteniendo el control total sobre los datos, las políticas de moderación y la administración de la comunidad sin depender de una estructura corporativa única.

El crecimiento exponencial de la red ocurrió a mediados de 2023, tras los cambios en la política de precios de la API de Reddit, lo que provocó una migración masiva de usuarios hacia el Fediverso. Técnicamente, Lemmy está escrito en el lenguaje de programación Rust para el servidor y utiliza el framework Actix, mientras que el front-end está desarrollado en Typescript con Inferno. Esta arquitectura permite un manejo eficiente de recursos y una alta velocidad de respuesta en comparación con otras plataformas de microblogueo. Actualmente, la red cuenta con miles de comunidades activas organizadas por temáticas que van desde el software libre hasta la fotografía, consolidándose como el principal nodo de foros federados a nivel global.

To me, it feels like there should have been something that is a common parent of both 'Object' and 'Link'.

That just had the "name", "nameMap", and "preview" fields (along with "id" and "type, of course) — since that is what 'Object' and 'Link' share in common.

I'll just call this common parent: 'Entity'.

It could have even been an opportunity to talk about how to handle unknown types.

Para hacerlo entendible #activityPub es un protocolo que usa peticiones HTTP basada en un formato concreto que luego en tu aplicativo adaptas a tu conveniencia (teniendo en cuenta si recibes o mandas, inbox u outbox).

Por si queréis hacer aplicativos compatibles con el protocolo ActivityPub y os molara hacer algo federado. Hay como unas acciones sociales concretitas que se le puede dar uso para la interoperabilidad.

Acabo de enterarme de que en @nextcloud están implementando una red social compatible con #ActivityPub, por lo que si tienes un servidor Nextcloud, todos tus datos quedarían allí. Y si es autoalojado, tienes de hecho una instancia autoalojada del fediverso.

Existe un nuevo proyecto llamado #Holos que brinda la facilidad de tener tu propio servidor del #Fediverso en tu dispositivo móvil. Puedes seguir el proyecto en:

➡️ @HolosSocial

La web oficial explica cómo funciona:

Para calmar expectativas, aún está en sus etapas iniciales y orientado a personas con conocimientos técnicos por ahora. Sin embargo, será interesante seguir su evolución 🙂

Holos es creado por los desarrolladores de la aplicación móvil para Mastodon/Fediverso #Fedilab.

I sometimes picture fediverse as one of these old horseracing toys from the 50s, where the horses represent all the various perspectives and expectations people have of the fediverse. There is no horse to bet on, positions change all the time, horses change tracks randomly. And furthermore there no finish line, the race is an endless slog. The prize of a robust #ActivityPub protocol forever out of reach, getting more elusive as time progresses.

@fox @silverpill @raphael @julian @mariusor

Yes. I tooted about the need for Grassroots open standards and Grassroots standardization this morning..

https://social.coop/@smallcircles/116147786851664068

In a decentralized grassroots movement, somewhere there needs to an aggregation of the solution artifact. In this case a robust, comprehensible #ActivityPub standard that can be readily implemented in libraries, frameworks and SDK's upon which then subsequently #SocialNetworking solution design can take place.

This is not centralization, this artifact can be federated. But there must be a place of convergence where consensus on protocol design comes together.

There might be a crowdsourced ActivityPub 2.0 specs + documentation site, plus a process around it to make it work.

I’m building a new tool and looking for volunteers to test it! A #fediverse linktree. (UPDATE: https://hub.vocalcat.com )

It’s designed for two types of people:

Normies / newcomers – Think of it like a free, privacy-respecting Linktree. No trackers, no ads. But here's the cool part: it's a Trojan horse for the fediverse. Your profile link is itself an ActivityPub actor. That means people can interact with it directly in the fediverse, and it encourages exploration of open platforms.

Fediverse users, If you have multiple accounts (#Mastodon, #Pixelfed, Loops, a federated blog…), you know the struggle: sometimes you just want one persona to follow. This tool gives you that. It doesn’t post on its own (read-only), but it boosts all your other accounts and even has its own #ActivityPub inbox. PLUS it can receive and show your badges issued by @badgefed !

Interested in testing? Right now it only supports mastodon authentication, so if you have a mastodon account reach out in private mention for the invitation code.

¿Sabían que Write.as no es solo una plataforma de blogs minimalista, sino uno de los pilares de la publicación larga dentro del Fediverso gracias a su integración nativa con el protocolo ActivityPub?

Lanzada originalmente a finales de 2014 como una herramienta enfocada estrictamente en la privacidad y el anonimato —donde ni siquiera era necesario crear una cuenta para publicar—, la plataforma evolucionó para permitir que cada blog funcione como una cuenta de red social federada. Esto significa que un blog en Write.as posee una dirección de usuario con el formato @usuario@write.as, la cual puede ser buscada y seguida desde instancias de Mastodon, Pleroma o Friendica como si se tratara de cualquier otro perfil, pongo como ejemplo mi propio blog https://text.tchncs.de/mdtblogmx/ que como verán esta en la instancia wtite.as de text.tchncs.de el cual puede seguirse desde cualquier cuenta del fediverso dándole follow a @mdtblogmx

La arquitectura de Write.as se basa en el software de código abierto WriteFreely, lo que garantiza que los artículos publicados se distribuyan automáticamente a los "muros" o líneas de tiempo de los seguidores en el Fediverso, permitiendo que las interacciones como "me gusta" o "impulsos" (boosts) se sincronicen entre servidores distintos. A diferencia de las plataformas de blogs tradicionales que dependen de lectores RSS o boletines de correo, Write.as utiliza la infraestructura descentralizada para convertir un texto estático en un objeto social dinámico que puede ser comentado y compartido a través de diferentes plataformas compatibles. Esta integración permite que el contenido extenso y analítico recupere visibilidad en un entorno dominado por mensajes cortos, manteniendo la interoperabilidad sin rastreadores ni publicidad.

Learning some of the secret backend sauce of NodeBB. It uses a relay - FediBuzz - to pull content from specific hashtags into its federated forums.

I knew that when I tagged #ActivityPub it ended up showing in activitypub.space, now I know how!

Alt...

A blurry slide explaining the success of the activitpub forum on NodeBB.

@reiver @thisismissem @mfru

I made a diagram yesterday that contrasts #ActivityPub and #SolidProject that is I think interesting to consider.

In the past I've been very active on the Solid forum, and tried to get a collab going with #SocialHub community. A number of points that existed then, are still issues today I think.

Like, though anyone could participate in the standards process via chat, the Solid team and Inrupt were not really interested in their community, hardly giving attention while people were building interesting stuff there.

Also at the time basically all available code was Javascript, making Solid uninteresting or hard to access for other language devs.

But I think biggest issue was that Solid didn't know what it was. It was positioned as 'personal data vault' on the landing page then (but not using this term), but was 'secretly' TBL's desire to reboot the #SemanticWeb. The new web would be all 'Solid apps'. But the adoption strategy for that didn't exist.

"A guide to implement ActivityPub in a static site (or any website)" by @mapache

#ActivityPub #ActivityStreams #FediDev #FediDevs #Fediverse

I suspect that there is an error in the Turtle specification, in the section shown in the screen-shot.

(It relates to JSON-LD, which ActivityPub / ActivityStreams is built on.)

I suspect that "PN_CHARS_BASE" is an error.

Because other parts of other specifications seem to not make sense if it is.

I suspect that maybe it should have been "PN_PREFIX" instead.

#ActivityPub #ActivityStreams #RDF #JSONLD

Alt...

2.6 RDF Blank Nodes RDF blank nodes in Turtle are expressed as _: followed by a blank node label which is a series of name characters. The characters in the label are built upon PN_CHARS_BASE, liberalized as follows: • The characters _ and digits may appear anywhere in a blank node label. • The character . may appear anywhere except the first or last character. • The characters -, U+00B7, U+0300 to U+036F and U+203F to U+2040 are permitted anywhere except the first character.

It is a lightweight, privacy-first Fediverse client for iOS, built around a simple idea: fast, small, predictable behavior, and first-class support for snac.

What makes it different:

• snac-first by design, not "compatible by accident"
• Works with all Mastodon API compatible software, including Mastodon, snac, GoToSocial, Akkoma, and others
• EXIF stripping on upload (HDR and orientation preserved)
• Optional on-device alt text generation via Apple Intelligence for your uploads and for images in your timeline
• Markdown posting for snac
• Granular notifications, grouping, multi-account
• Blocking and moderation tools
• Very small footprint, very low RAM usage

Alt text generation happens entirely on device via Apple APIs on supported hardware. Nothing is sent to external services.

It is built around my own workflow and priorities. It may not be for everyone, and that is perfectly fine.

Important note:
MastoBlaster will always be free for BSD Cafe users, illumos Cafe users, and for anyone connecting to a snac instance, including self-hosted ones.

The app is already usable, but this is still a test phase. I am looking for feedback, bug reports, and real-world usage insights.

There is a larger discussion about fixed-point numbers versus floating-point numbers.

And that, ALL programming-languages should have fixed-point numbers built into them.

And that, programmers should be warned against using floating-point numbers in all but a set of very specialized situations — where inexact math is OK.

For most programmers in most situations inexact math is NOT OK. And, they should NOT use floating-point numbers.

#ActivityPub #ActivityStreams #JSONLD #RFC7159 #RFC8259

This is likely (directly or indirectly) the fault of a single paragraph in IETF RFC-7159 / RFC-8259 (shown in the attached screen-shot).

(And note that, there is a difference between JSON and IETF JSON. JSON did not have this. IETF JSON does.)

That paragraph (in the IETF RFC) was NOT a requirement. But, others made it a requirement — including JSON-LD.

RE: https://mastodon.social/@reiver/115956356584464586

#ActivityPub #ActivityStreams #JSONLD #RFC7159 #RFC8259

Alt...

This specification allows implementations to set limits on the range and precision of numbers accepted. Since software that implements IEEE 754 binary64 (double precision) numbers [IEEE754] is generally available and widely used, good interoperability can be achieved by implementations that expect no more precision or range than these provide, in the sense that implementations will approximate JSON numbers within the expected precision. A JSON number such as 1E400 or 3.141592653589793238462643383279 may indicate potential interoperability problems, since it suggests that the software that created it expects receiving software to have greater capabilities for numeric magnitude and precision than is widely available.

This is from the JSON-LD spec.

ActivityPub / ActivityStream are based on JSON-LD.

I think it was a very bad idea for JSON-LD to define "number" this way!

It makes it so numbers with fractional values are inexact & lossy.

This include values that are common for money.

For example, neither 0.10 and 0.20 can be represented exactly. So, 0.10 + 0.20 does NOT equal 0.30!

It should have used FIXED-point numbers rather than FLOATING-point.

#ActivityPub #ActivityStreams #JSONLD #RFC7159 #RFC8259

Alt...

number In the JSON serialization, a number is similar to that used in most programming languages, except that the octal and hexadecimal formats are not used and that leading zeros are not allowed. In the internal representation, a number is equivalent to either a long or double, depending on if the number has a non-zero fractional part (see [WEBIDL]).

This is how #Holos currently handles #E2EE DMs over #ActivityPub. Holos is a project we develop alongside #Fedilab.

https://holos.social/e2ee

#HolosSocial

@sk@utsukta.org mentioned in another thread that the way Hubzilla and threadiverse software handle group discussions is incompatible.

It got me thinking about whether that is true. At its core both FEPs (171b and 1b12, respectively) rely on a central "distributor" node to send activities to recipients.

@silverpill@mitra.social did further comparisons in thr text of 171b itself:

Announce activity is used instead of Add. Conversation and related activities are synchronized between participants, but conversation backfilling mechanism is not specified.

The questions here are:

1. If threadiverse software federated out an Add in addition to Announce, would that satisfy basic synchronization (not backfill) requirements laid out by 171b?
2. Is there any reason why Announce could not be used to facilitate private federated group discussions as well? Assuming visibility maintains scoped to addresses, I don't see any immediate reason why not...

With #HolosDiscover we checked multiple criteria before indexing: "indexable" enabled, account not locked, no #nobot or #noindex in bio, not in opted-out list, only public posts. Every deletion, edit or block was processed instantly via #ActivityPub.
Google uses that same "indexable" flag but ignores everything else, keeps deleted content cached for weeks.
We shut it down after pushback. Was that the right call? Don't hesitate to share, this concerns the whole Fediverse.

In the old blogging software I created back in the 1990s, I had a handful of posts types

There was a type of rich-text oriented post that had a title. (Article)

And, there way another type of rich-text oriented post that did not have a title. (Note)

(There were also other types of posts, but they aren't relevant here)

These 2 types of posts were rendered / displayed differently

I.e., my 1990s software already had this distinction

#ActivityPub #ActivityStreams #FediDev #FediDevs #Fediverse

I've seen an ongoing debate between "Note" versus "Article" in ActivityPub / ActivityStreams.

When is something a "Note"‽
When is something an "Article"‽

Personally — I would probably have made the distinction this way.

An "Article" has a title.
A "Note" doesn't have a title.

(In ActivityPub / ActivityStreams, a 'title' seems to tend to get represented in the "name" field.)

#ActivityPub #ActivityStreams #FediDev #FediDevs #Fediverse

#ThoughtProvoker

The current fediverse is an evolutionary dead-end for 2 reasons:

1. It has painted itself in a small niche of decentralizing typical social media use cases, by means of post-facto interop and the introduction of protocol decay.

2. Lacking a proper grassroots standardization process, and with the primary mechanism for fediverse extension being only post-facto interoperability, there is no way out.

Congratulations to the early adopters, who managed to "cross the chasm" with their own app platforms. It took true grit to become deep #ActivityPub experts, and plug holes needed for your app, but you have made it. Post-facto interop works in your favor now. You are unrestrained to productively add more features in your app, and put them on the fedi wire for others to deal with.

To avoid fedi to become less and less attractive to newcomers, we must now consider:

“Why do we want to grow the open social web, and for whom?” -- @ben

http://coding.social/blog/shared-ownership/

number of files generated by snac is huge, but i don't care that much anymore.

$ du -hd0 /var/snac

sometimes i use snac command line, but mostly snac web ui and nothing else.

someday maybe i'll try to build some minimalist #activitypub server, but looks like a lot of work :)

After quite some time, I’m finally ready to share this.

MastoBlaster is now available in public testing on TestFlight.

It is a lightweight, privacy-first Fediverse client for iOS, built around a simple idea: fast, small, predictable behavior, and first-class support for snac.

What makes it different:
• snac-first by design, not "compatible by accident"
• Works with all Mastodon API compatible software, including Mastodon, snac, GoToSocial, Akkoma, and others

#MastoBlaster #iOS #Fediverse #Mastodon #snac #snac2 #Akkoma #GoToSocial #ActivityPub #OwnYourData

After shutting down #HolosDiscover, we're rethinking the approach with #HolosIndex: users explicitly opt in by adding #HolosIndex to their bio with interest tags, then submit their profile. No assumptions, no default settings.
This will power interest-based discovery across the #Fediverse, helping people find each other through shared interests. Still all through #ActivityPub of course, with real-time deletions and updates.

Maybe something to clarify with #HolosSocial. There is a full moderation system like on any Fediverse instance. Moderators can ban accounts. But relays are dumb by design: your identity and data belong to you, not to the relay. A ban is like a relay going down, you don't lose everything. You can move to another relay and keep all your followers, following, and data. With a custom domain the transition is seamless, otherwise it works through standard #ActivityPub migration.

Why do we want to grow the open social web, and for whom? @ben says the value is in protocols that allow people — all people around the world — to build and own communities that address their needs. "The only way to achieve that is to not just co-design with them but distribute equity. They must be full co-owners of the open social web," he writes.

Heh, heh. Tonight I stumbled upon a hidden little feature in Fedify's CLI.

If you run `fedify nodeinfo mastodon.social -b` you get a cute little ascii art representation of the instance's logo.

Happy to see a bit of fun mixed into these fedi tools!

@fedify #ActivityPub #Fediverse

Alt...

A terminal, with the command `fedify nodeinfo {serverName} -b` entered, it shows an ascii art representation of the logo.

Recently, there was a question by @taylorlorenz about how you explain the Fediverse to someone who doesn't use it.

And usually, what we tend to do is we talk about servers and decentralisation and federation and ActivityPub and all these highly technical concepts.

I've been thinking about it, and all that technical stuff is really impressive work by people far more clever than I'll ever be.

But for me, that technology is a facilitating thing. It's like trying to describe how a bicycle works, rather than why you ride it.

Instead, what the Fediverse is, is a place to have conversations online without algorithms, AI, and ads getting in the way.

Which is increasingly a rare thing online.

Almost the entirety of the internet, from SEO on the web to YouTube to TikTok to Spotify to Instagram and X and Facebook, has been turned into a race to game an algorithm designed to sell ads.

What makes the Fedi unique is that it's not that.

And I suspect if you're trying to persuade someone to try Mastodon (or Lemmy, or Pixelfed, or GtS, etc), you'll get a lot further explaining it as algorithm-free, ad-free, AI-free conversations, rather than trying to describe a decentralised protocol.

#Fediverse #Mastodon #ActivityPub

There's a lot of energy on the #Fediverse right now to discuss/find a #Federated alternative to #Discord using #ActivityPub.

@strypey suggested that I put this out there to anyone who's thinking about it. We could probably rebuild most of Discord's features as an #Emissary inbox without doing a lot of back end code.

I'm too swamped to start on this right now. But if you're a great HTML+CSS designer, I'm able to give some time to a team who wants to take this on.

Overview of the fedi-relay gyptazy instance for the Fediverse

This morning I promoted nolto.social, a platform that was made - at least I thought so, to be a Fediverse based alternative to LinkedIn. As I'm getting more and more annoyed by LinkedIn and all the useless posts over there, I was happy to find an independent alternative.

nolto.social still worked this morning, but when I came back later; i found the project deleted and at least when you are viewing the website from your smartphone, you see a message from the developer of nolto.social where he states that this project was never meant to grow. Obviously this was just a one person project who became overwhelmed by the success of the platform and by the fact, that companies started creating profiles and nearly 1000 people joined within a short time period. But now it seems that this project ran out of control and the maintainer decided to pull the emergency break. He is also talking about negative feedback he received for the platform and even personal harrassment.

It is sad that a promising project like this had been terminated, but I can understand what made the maintainer doing so. Managing a business platform can become a fulltime job quite fast and it also requires technical ressources and money to run these resources.

I firmly believe that we need an alternative to LinkedIn. I believe that people don't want all this bullshit posts just created to please the algorithm and to generate likes and feedback. And I believe that people would like a business network which is nothing else than a business network - no space for bursting egos and self promotion, but a space for connection and serious discussion.

Fediverse would be the ideal space for this. But as we know, if business networks are successful, they require more and more attention, more ressources, more money. And at this is the problem. When you need money to run your social network, it's tempting to ask yourself how you could generate money by using the ressources you already have, which are user data...

I don't see a solution for this now, just sharing some thoughts.

I would even host it at home, but it seems like huge parts of the Fediverse are IPv4-only, and #ActivityPub behind Dual-Stack Lite doesn't sound like fun.

With https://discover.holos.social we may have highlighted that many Fediverse users don't pay attention to their default settings. We built a fully respectful search engine that only relies on #ActivityPub, with instant deletion, updates, and indexing only consenting users. We will likely shut down the service, but the source code will remain available as we believe the approach is ethical. That same indexable setting already lets Google index your posts and keep them cached long after deletion.

The walled gardens of the big tech-platforms will be their demise. So much innovation is lost because of the need for control.

Really, the U.S. platforms are not forward looking. The have hit reverse a long time ago, going full speed towards history.

In the previous century I could pick up a phone and call anyone. Try that with the big platforms. NoT wiTHout a DeAl!

Open protocols are the way ahead.

Your Home Feed is the inbox of an ActivityPub actor — in particular YOUR ActivityPub actor.

There could be an actor for each hash-tag, too.

You could even do Del.icio.us like things — and have actors for intersections of hash-tags, too.

These hash-tag actors' inboxes would need to be readable by anyone.

...

This could be a more ActivityPub like API alternative to Mastodon's "GET /API/v1/tags/{name}" API.

@lps
That would be interesting indeed. We have an open feature request for this (https://github.com/AntennaPod/AntennaPod/issues/7698) but there are some technical and legal challenges. No decision has been made yet on whether this might be implemented (if a PR would be accepted).
But did you know you can already open ActivityPub comments (in the browser) for episodes that support it? In the player screen you can tap on the three dots and then 'Show comments'!

The enshittification continues. I remember @evan shared some thoughts about using ActivityPub to develop a federated #dating app. In some ways, it's the ultimate test for UX, onboarding, etc, in federated networks. Some challenges;

* it requires helping people meet within a geographical range

* it requires a critical mass of attractive people using it to attract others (the bootstrap problem dialed up to maximum)

* Trust & Safety are *essential*

Anyone in my followers list on a server that has secure fetch enabled? I want to use it to test my proxyUrl implementation for client to server #ActivityPub. :D

RE: https://mastodon.social/@reiver/115945290105913697

The resolving of a Fediverse ID to one or more cryptographic public-keys could happen via the activity-file for the user.

A JSON-LD namespace (separate from ActivityPub) could put the cryptographic public-keys into the activity-file.

But, I think we would need more information than what the 2 current methods for including cryptographic public-keys currently support.

RE: https://mastodon.social/@reiver/115945290105913697

Right now, Fediverse IDs resolve to HTTPS URLs.
For example, the Fediverse ID:

＠reiver＠mastodon.social

Resolves to HTTPS URL:

https;//mastodon·social/users/reiver

...

If we wanted cryptographic public-keys to serve as a basis of Identity on the Fediverse, then —

We would (similarly) also need a Fediverse ID to resolve to one or more cryptographic public-keys

...

#ActivityPub #Cryptography #FediDev #FediDevs #Fediverse #JSONLD

I dream of being able to store my online social presence, identity, and history just as — an (organized) set of static files.

A set that I control.

And, I can (if I want to) host myself. (I.e., I am the "source of truth" / "origin" for my files.)

If you cannot get (most) regular people to write JSON-LD, JSON, or even HTML —

But, you might be able to get them (regular people) to write something similar to Markdown and INI —

Then, are there ways you could (explicitly or implicitly) encode JSON-LD type information, such as ActivityPub, into a Markdown-like or INI-like file — in a way where they (regular people) would likely include it?

I suspect — probably yes.

El tipo de aplicaciones/servicios que todavía consigue emocionarme con la tecnología 😍

@HolosSocial es una red completamente descentralizada basada en #ActivityPub que crea un servidor en el móvil que comunica con el resto de servidores a través de un relay.

Podría entenderse como un servidor de Mastodon, p. ej., con un único usuario ejecutándose en el dispositivo móvil donde se almacenarían todos sus datos.

A client to server protocol, or "Social API" This protocol permits a client to act on behalf of a user. For example, this protocol is used by a mobile phone application to interact with a social stream of the user's actor.

#owncast is FOSS and awesome. so why did #ATproto people build smoke signals? same reason #bluesky didn't just build off #ActivityPub I assume. something something don't mention VC etc.

On stage now, @django — arguing for widespread adoption of ActivityPub client-server (C2S) protocol.

I agree with him.

At the very least, to make extension of ActivityPub through JSON-LD namespaces possible.

But also to decouple Fediverse client development from Fediverse server development.

And more.

So, not just Decentralized Social (DeSo), but instead —

Decentralized Social (DeSo), Federated Social (FeSo), Localized Social (LoSo)

The goal is 'social' that is simultaneously — 'Decentralized', 'Federated', and 'Localized', all at the same time.

Federation is the word we use to describe that act of bringing together and connecting these separate Decentralized, Localized communities.

This is where protocols such as ActivityPub, ActivityStreams, etc come into play.

Federation is a voluntary choice.
But, so too is Defederation, if desired.
