What you linked to is not really evidence, just an unsubstantiated allegation. Over the top public shaming is something that should be pretty easy to provide direct evidence of. When Linus Torvalds does it, it gets repeatedly brought up in forums like this for many years.

I have no reason to believe it is a lie, and it sounds plausible. A 'public shaming' should be a last resort is my assertion, and I stand by it.
