I keep seeing this type stuff but neither peertube or friendica are genuine replacements at this point, mastodon is weaksauce compared to akkoma or a misskey fork, and loops is alpha software. also yes signal is centralized but it just works and has contact discovery so it owns matrix and xmpp when compared to whatsapp. basically none of this stuff is truly ready

matrix too has contact discovery, if you add your phone number. most users don’t, and that tells me something
