I am completely on your side. Matrix did improve upon the state of XMPP in 2012. But XMPP improved too and therefore the problems we had 2012 are not relevant anymore today. There is just one big problem with XMPP nowadays: Very few people are interested in XMPP as everybody wants to learn the new shit aka Matrix. And actually, that is the one thing I blame the Matrix devs for. Instead of improving an existing open IETF standard they decided to invent something new and split the community. Technologically, Matrix is neither better nor worse than XMPP, as far as I can tell, but splitting the community wasn't such a brilliant idea.
