@f275d986 there are many more protocols out there than just XMPP and Signal, what about say Nostr, WebRTC  and others? So which one would it be then? That is very likely why we have so many - nobody ever made any decision for everyone, so all platforms went their own way. That really needs to change to at least have something to interconnect. 

 @771c7916 What I meant was an example of some of the oldest one from the IRC times. WebRTC is a piece of unsafe in many ways, privacy unfriendly junk.
