Monero's home is right now on Matrix. I'm disputing that. This is a video follow-up with some of the replies from last time.
If you are new, XMPP and Matrix are two competing federated end-to-end encrypted messengers. XMPP is far better, on server cost decentralization, speed over Tor, degoogled push notifications, multi-identities, and overall privacy. So if Matrix is inferior centralized bloatware, why is it more popular? Especially among XMR techies, who should in theory understand these concepts.
This brand new video gives a quick overview of the technical reasons that XMPP is the gold standard king of federation. And it briefly discusses how Matrix manages to push it’s agenda:

Some critics will say that “Matrix is a complete package, while XMPP is fragmented”. This is essentially propaganda, because all the XMPP clients interact (Dino, Gajim, conversations, monocles). The only one that doesn’t interact is OTR encryption from pidgin which provides an alternative for hardcore cypherpunks who want to destroy the encryption keys when the conversation is done. So because one single client has an alternative use case, the Matrix cheerleaders want us to fill out Google Captcha spyware to register on Matrix.org because it costs so much to self-host.
Moderation might be an issue with such a platform, who's responsible for cleaning spam, csam, etc? Giving someone that power will centralize the system anyways. The current federated system works pretty well in my opinion.
