I found this to be a pretty good rebuttal to that

The summary at the end of

"Get over yourself. You are not as special as you believe yourself to be.

At that point, I gave up on your pathetic and emotional diatribe. Your piece is devoid of any logic, reason, or sense and serves as a way for you to virtue-signal to the rest of the world how much of a “stand-up guy” you are."

Is spot on how I read that Medium post.

I found nothing of value in the Ex Googler's commentary.

I think he's thought it through enough to see the implications. And that ex-Googler has a fairly draconian, authoritarian view of groupthink.

I don't think that ex-Googler read the document. Nothing he attacks him on seems to be in it.
