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 just shows how little Eugen understands the privacy risks. Why just blocking Meta's Threads won't be enough to protect your privacy once they join the fediverse has an example of how federating with Meta can expose private data. And, data can be public but hard to discover (a profile for somebody who only makes followers-only and local-only posts); federating with Threads adds exposure.
If they really wanted to they could already do that by setting up an instance and not publicly announcing it.
