Beeper is an app that unifies all the messaging protocols you mentioned (and others) into a single app. They are not introducing another protocol.

Universal in this context is referring to the ability to use a single app across protocols rather than the ability to use a single app across platforms.

I miss the days of jabber being able to senselessly talk to aim, msn, yahoo, icq, etc. All chat contacts in one account.

Jabber transports, they were great.

Ok, I get it.

It's what EU mandated and from March '24 all major chat apps have to be able to communicate with each other.
