    @thisismissem No offense to anyone that has made any protocol, but I don't give a shit which protocol it is as long as it's an open protocol we can access openly, freely, forever. I think the fear with AT Protocol is that Bsky might enshitiffy it? I don't know enough about AT to even know if that's possible.

    @firesidefedi yeah, one could argue that, but there's so many other people building in the AT Protocol ecosystem that it'd only affect maybe one part of the network, there already exists alternative AppViews, Clients, Relays, and PDS's, especially if we look at the wonderful work from the Blacksky team (blackskyweb.xyz)

      @nik I'd received multiple people saying yes, and been granted approval to merge. As it's not a specification change, the 14 day CFC did not look like it applied, and it did not need all members to agree or co-sign.

      @thisismissem

      It is inappropriate to create a "statements" directory in the repository, with this as the only item in it, making it seem as if it was an official SWICG statement.

      Things like these are, at the very least, called a "draft" until they officially pass. You are doing your cause (to which I object anyway) no favor with this fishy activity.

        @stefan that visualization isn't particularly great at showing how (de)centralized it is though.

        Things are not to scale in it: Single user PDS is as much as 1/50th the area of a Bluesky Corporate PDS with almost 400,000 users.

        @ikuturso @stefan @mastodonmigration @thisismissem

        and?

        if it enshittifies, people will simply migrate to other PDSes.

        and those PDSes will start looking at different relays

        the only thing i am concerned about is the appview thing, but i believe that deals with protocol content rather than any actual implementation (where the real nub of the control is)

          The problem is a matter of scale. There is no way for 99% of users to "simply" move anywhere.

              aye, there's the rub

              even on mastodon, migrating to another server is hard.

              you have to follow a 50 step process, create another account, then move all your stuff...

              it would be hella nice to have a one-click button that simply moves all your shit to another server.

                @mastodonmigration @breathOfLife @ikuturso @stefan Blacksky already recently managed a mass migration away from Bluesky hosted PDS's for their community. Similar could happen if needed for other communities.

                        Yes, the Blacksky migration was impressive. It still did not change the overall percentage distribution numbers very much. It seems like proponents of AT Protocol should welcome criticism of too much dominance of Bluesky PBC and support more independent Blacksky type efforts.

                        Why, if Bluesky is actually serious about wanting AT Protocol to be decentralized, is there not more overt support for moving the numbers in a truly meaningful way.

                          @mastodonmigration @breathOfLife @ikuturso @stefan there's also NorthSky in Canada that's building on Blacksky's work, and I'm sure there'll be something similar in the EU too

                            Recently there has been a lot of discourse about ActivityPub and AT Protocol which has been quite dividing and heated.

                            Yesterday at the Social Web CG meeting (the group that maintains the ActivityPub and related specifications), I proposed releasing a statement that counters the narrative that one of these protocols must win, when both protocols can co-exist and have a lot to learn from each other.

                            The statement has been co-signed by various members of both Social Web CG, SocialCG, and the AT Protocol community.

                            β€œWe do not win by tearing each other down, which only emboldens and empowers those who do not want either protocol to succeed.”

                            β€œArguing between us only emboldens those that seek to derail and destroy efforts to build an open social web.”

                            You can read the full statement here:
                            https://github.com/swicg/general/blob/master/statements/2025-09-05-activitypub-and-atproto-discourse.md

                            @thisismissem i strongly disagree with this. bluesky is only decentralized on paper, and in reality, only a tiny fraction of its users aren't reliant on bluesky's hosting. if bsky.social suddenly disappears, almost all of ATProto goes down with it. the same can't be said about mastodon.social, which is the biggest instance, but the fediverse will survive if it suddenly disappears. according to https://arewedecentralizedyet.online, only 55,500 people are on non-bluesky owned PDSes, so blueksy could just (1/3)

                                @ikuturso @mastodonmigration @breathOfLife @stefan there's plenty of DID methods that have been developed; There are some people using did:web, there's also did:webvh β€” but there's definitely still more work to do in this space.

                                I think ActivityPub could theoretically adopt did:web or did:webvh as an alternative to webfinger.

                                  @mirabilos @thisismissem @ahltorp And even without that, the choice of a copyright license also doesn't means anything about the ecosystem and it's architecture.
                                  BlueSky is built for massive silos with technically allowing communication between them but that's an admin setting.

                                    @thisismissem turn off federation, and force everyone else back onto bluesky-owned PDSes. facebook did the same thing before. facebook messenger used to be part of XMPP, a decentralized instant messaging protocol, allowing people on FB messenger to message people who didn't use FB messenger. but one day, facebook just turned off federation (source: https://fedi.tips/its-a-really-bad-idea-to-join-a-big-server/#:~:text=There%20is%20also%20a%20precedent,Facebook%20to%20switch%20off%20federation), cutting off people from outside messenger, and making it so messenger users could only chat with other messenger users(2/3)

                                      Yes, the Blacksky migration was impressive. It still did not change the overall percentage distribution numbers very much. It seems like proponents of AT Protocol should welcome criticism of too much dominance of Bluesky PBC and support more independent Blacksky type efforts.

                                      Why, if Bluesky is actually serious about wanting AT Protocol to be decentralized, is there not more overt support for moving the numbers in a truly meaningful way.

                                      the reason that blacksky have their own relay implementation is because bluesky NEVER RELEASED THEIRS IN THE FIRST PLACE.

                                      they left half the protocol unfinished in a deliberate attempt to centralize control.

                                      then rudy fraser decided "fuck that" and proceeded to build atproto.africa, severely fucking that attempt six ways until sunday and putting atproto on the map as a serious protocol as opposed to a complete joke.

                                        BlueSky is built for massive silos with technically allowing communication between them but that's an admin setting.

                                        @lanodan @mirabilos @ahltorp you mean MIT / Apache 2.0 license? https://github.com/bluesky-social/atproto/blob/main/LICENSE.txt

                                        The social-app repository is also under what appears to be a MIT license except where explicitly noted otherwise.

                                        And Blacksky's rsky is under Apache license: https://github.com/blacksky-algorithms/rsky/blob/main/LICENSE

                                          @thisismissem I would add that both protocols support use cases that the other protocol has a hard time addressing. ActivityPub, for example, is much better at point to point communication where no third party overhears what is happening. ATproto, for example, can be used to build β€œglobal trending” or a global index much more easily.
                                          I would not be surprised if at the end of they, the open social web would simultaneously end up using both, in a complementary fashion.

                                          @thisismissem @j12t It follows that AP is best suited to talking to friends, while AT is best suited to talking to strangers. And there is a far larger demand for the former than the latter. So I'd predict a future where AT evolves into a high-performance enclave embedded inside AP.
