> By the way, iMessage is XMPP. Whatsapp is XMPP. Just artificially closed. Long etc. I've heard these rumors, but they don't seem to be true. WhatsApp seems to have moved on a long time ago (to a binary format wrapped in an implementation of the noise protocol framework) and I find zero indication iMessage was ever XMPP. But that's besides the point. XMPP is great for a uniform ecosystem (in fact, a lot of XEPs are some company standardizing their use-case), but awful if you allow federation and third party clients.
