My previous text just mentions Mastodon limitations. Quite frankly couldn't really care less about ActivityPub or what it could do similar to Nostr (not even doing so today is already a bad thing in itself). You yourself repeat the same castrating limitations "so long as you own your domain". And that's the point. Most people: + don't own domains + don't want to own domains + don't need to own domains for the sake of identity Nostr solved all that for free with private/public keys, a simple and battle-proven approach available since decades.
