When Meta launched their new Twitter competitor Threads on July 5, they said that it would be compatible with the ActivityPub protocol, Mastodon, and all the other decentralized social networks in the fediverse "soon".
But on July 14, @alexeheath of the Verge reported that Meta's saying ActivityPub integration's "a long way out". Hey wait a second. Make up your mind already!
From the perspective of the "free fediverse" that's not welcoming Meta, the new positioning that ActivityPub integration is "a long way out" is encouraging. OK, it's not as good as "when hell freezes over," but it's a heckuva lot better than "soon." In fact, I'd go so far as to say "a long way out" is a clear victory for the free fediverse's cause.
That's incorrect. Followers-only posts (and local-only posts on instances that have them) aren't public. Profiles that don't make public and unlisted posts aren't discoverable. And, as Threat modeling Meta, the fediverse, and privacy discusses, there are plenty of things that could be done to reduce the amount of data that's public.
Also, that's only one of the many reasons people oppose federating with Meta.
