• Oh, I get that theory, though I’m not sure I completely agree. Either way, unless I completely misunderstand how ActivityPub works, their instance can effectively be isolated to its own little sandbox depending on how many other instances decide to share with them. Further, if you’re on an instance that decides to share w/ Meta’s, you can skip over to another one that doesn’t. So Meta can be isolated by instance owners and/or users.

    • I’m no ActivityPub expert, but what people more knowledgeable than me have pointed out is that this results in fragmenting the Fediverse, which ends up hurting it on the long run. I’d definitely not want to be on an instance that federates with Facebook, but I also wish none of the larger ones choose to do so.

      • Not really. If they created a reddit or twitter alternative without ActivityPub support, it would have the same effect but without the ability to join them. A big player creating competition is a huge acceptance barrier for the fediverse outside of their huge influence.
