Oh, absolutely not. Let me be clear, I do not question that the author was involved in the project and interacted with Google. I do not question any of the factual details in the article and my argument is not that he's lying. Total respect for him, his work at the time and even his opinions on how annoying and frustrating it was working with Google around.

What I'm saying is his perspective on the alleged failure of XMPP is specifically biased by his insider experience, that many of the examples he gives do not apply to AP, that the process he describes there is not EEE, that it's not the reason XMPP and Google Talk failed and that, as he admits throughout the piece, XMPP didn't in fact disappear or "die" after Talk's failure or because of their intervention.

An XMPP developer would likely have been delusional about the protocol he himself developed. But at the time I can assure you XMPP was completely irrelevant. AIM/ICQ/MSN/Yahoo! and maybe IRC were the tools of the day back then.

Because of actual competition (which XMPP had absolutely no part in) multi protocol messengers had their golden age then.
