Importantly, posts hosted and visible on Meta's server will be subject to Facebook's content moderation rules, which means those policies will likely have a sweeping impact across the Fediverse.

Is it just me or does that sound like anything on instances hosted outside of meta's own that can be merely seen from theirs? I'm all for moderation, the stricter moderation against hate-speech is part of why I joined Beehaw. But if I'm reading that right (I hope I'm not), then it seems like they plan to call the shots on other instances as if they have any say in what everyone else does right out of the gate.

Maybe what's meant here is simply defederation of entire instances and banning of problematic users like any other instance does, ok. But it could also mean pressuring admins to enforce Meta's TOS on a case-by-case basis which feels like the start of EEE tactics.
