Agreed about Matrix and Tox qualifying (not being centralized). I can't vouch for Tox from a security standpoint (haven't looked at the details), but I can guarantee that it's not ready for widespread use (esp. on mobile where P2P messaging still needs a breakthrough). Matrix is fine. In my biased opinion, it's just XMPP with more steps, more overhead and a less diverse ecosystem. Also, its security story is no better than XMPP so it's funny that we came to that from "XMPP, encryption is optional and not even the default", where that's practically truer for Matrix than it is for XMPP.
