XMPP is a good machine for bait and switching. I discovered it after building my own AOL-like chat systems from scratch in high school, in VB, C, PHP, etc (many iterations) and engaged heavily. To this day all I hear when people talk about why not XMPP are lazy excuses. No doubt they come out as blaming XMPP rather than the hard problems it's solving at scrum meetings. I built a chat app backend recently and was met by FUD from senior engs on the team when I proposed it, and hostility by the CEO who trusted them... forced to build an MVC-based node backend PoC which wouldn't have scaled if I didn't already know how to build chat systems (force="this discussion is over" and "if you don't like it you can quit" type comments... which I did).
