He and several others apparently did bring facts. Those tweets aren't available now it seems.
His argument wasn't even that great (because there is no good argument, and that's why one wouldn't take the bait if they actually like their job), and by then I'm afraid the axe had already been sharpened.

The facts are in replies, not standalone Tweets, so you have to know which Tweet to start with. From his profile, click on "I have spent ~6yrs working on Twitter for Android and can say this is wrong."
