This blog post by Ploum, who was part of the original XMPP efforts long ago, describes how Google killed one great federated service, which shows why the Fediverse must not give Meta the chance

Yes. A lot of that is going on with instances being blocked en masse for allowing too many spam/bot accounts without any corresponding high quality activity coming from users registered with that instance. It’s very much in flux right now, with instance administrators trying to figure out which metrics to use and what lists to trust, but I imagine a more mature/robust process will be used by most serious instances soon enough.
