@HistoPol It goes both ways. If you’re circumventing the Fediblock by mirroring @potus on another server, there’s no moral high ground when Threads mirrors an account from a server that Fediblocks them.
And of course, that probably will happen. However, many people believe want to de-federating Threads because they believe this will prevent Threads from accessing their public feed. And that’s just plain wrong.
Either way, I doubt the servers de-federating Threads will mirror his account on their servers because what these servers want, more than anything, is moral high ground.
