@hinterwaeldler I think an important point against the article was left out: jingle and video chat. That was a big one with the growth of high bandwidth connections. XMPP just did not work well, and to this day there is not a single XMPP client on Android with good Jingle support. The only one that ever came close was Jitsi. Why mess with Jabber when I can use Skype? People like open standards whether they know it or not, but they like things that work seamlessly even more.
