There has been a lot of chatter about the decision of some instances on Mastodon to pre-emptively block Meta’s purported new ActivityPub-compatible service: Dare Obasanjo: It’s a weird own …
A very detailed article about the whole Meta (Instagram/Threads) vs. Fediverse discussions. It's a long read, but well-worth it if you're interested in the subject.
While I fall on the other side of this debate (I'm pro-federation with Meta), this article helpfully distinguishes between people's conflicting priorities. For some users it's important to defend Mastodon as a community and a set of social norms. For me the goal has always been wide adoption of the ActivityPub protocol. Mastodon was just a useful way to kickstart adoption, and Meta adopting it would be a huge boon to the protocol.
I'm not personally very interested in a small community of like-minded people on a mini-Twitter. I want a mega-social network linking multiple services, including big corporate ones and small community-run ones, like email or podcasting (as someone else here mentioned).
This too should be a selling point for the Fediverse, no? There will be Mastodon, kbin, etc. instances that do federate with Meta, and some that don't. And that's fine, because the platform encourages the choice in freedom of association.
But, as demonstrated by the quotes that begin this article, there seems to be an abstracted, ideological opposition to the idea of anyone defederatinfg with Meta. I don't necessarily want "a small community of like-minded people on a mini-Twitter" either (we'll put), but I do want my information to not be (easily) accessible to corporations who openly intend to abuse it.
