The entire purpose of Nostr is about true censorship resistance and speech autonomy. That doesn’t exist with AP. Even if you self host, others can block your instance and no one will think twice about why the server is on the list.
That is by design in AP. If you self host and your instance gets blocked, that's between you and the other instance. You can still speak all you want, the other instance is just not listening any more. You've been excluded from the instance that blocked you because you didn't follow their rules. So participate in other communities and try to follow their rules and you probably won't be excluded.
"True censorship resistance" and "speech autonomy" sounds dangerously close to "free speech absolutism" ("freeze peach").
