This actually matches what I have seen. I think this whole thing is about people with entitlement issues that think whatever great thing they do deserves unconditional respect and admiration. And when it then turns out their idea was not so smart and Linus is telling them in language that cannot be misunderstood, they look for fault with him instead of themselves. The language argument is completely bogus. In fact, when Linus rants at somebody, he is not disrespecting them, as he always gives rational reasons. Disrespecting them would be to add them silently to an ignore-list.
My take is that the SJWs and the self-proclaimed geniuses just cannot deal with running into people smarter and more experienced than them. The Linux core-team is admittedly one of the most high-powered engineering teams on the planet. And yes, there quite a few decisions they made that I do not like, but these are details in comparison to the overall achievement.
