@evan there's a world of difference between "XMPP is what allowed GTalk to grow", which is absurd, and "Google used XMPP to help grow GTalk, and then dumped it", which is a pretty decent description of what happened IMVHO.
Either way, XMPP was far worse-off after that, in ways I do not believe it would be if Google never touched it.
And if we are not careful, same might happen with fedi and P92.
