No they didn’t. Google Talk had millions of users, all other XMPP clients combined had like 5. XMPP died when Google Talk stopped supporting it, but that wasn’t a case of Google Talk killing XMPP, it was a case of Google Talk being the only thing keeping XMPP alive.
Facebook and google killed XMPP that way, which is why people are very concerned regarding federation with threads.
However, I am not sure that this strategy worked that weight. Microsoft never killed competition from Linux and Mozilla
