I'd like to believe that one of the reasons Linus has that kind of reaction is because of the scope and impact his decisions and this kind of patches can have on people all around the world. This is a very specific situation, in which the advices in Sandya's article may not apply.

However, I fail to see how Sandya's observations are BS. A code review is a place to improve code and oneself, and there's a pretty large distinction between constructive criticism and sarcastic/aggressive comments. Being respectful/mindful of your colleague in that situation is in my opinion the minimal requirement.
