Yes, I had hope in the early 2000's with XMPP, but considering 20 years later we still have a fragmented ecosystem and none of the actors are willing to push for a federated network (even the open source, NPO, Signal!) is really depressing.
additional reminder that fb-messenger, whatsapp, imessage and probably a lot others started out as xmpp forks/dialects and even this was not enough to save us from the corporates.
