When most CEOs have a cow, a few people witness it and then they sanitize the message before releasing a PR statement of what the CEO would like to see happen. When Linus has a cow, it can end up on the front page of Hacker News with everyone talking trash about him.
As far as I know, he actually handles that piece of it remarkably well. Most people would not cope too well with such a situation. I have never heard of him then going on a screed about "assholes on Hacker News" or whatever. Instead, what I have seen is "polite" and "well behaved" people nastily referring to it as "the peanut gallery," which is incredibly insulting and dismissive. I have yet to personally see Linus do such a thing.
Given how much people here like to talk trash about him, I infer this suggests it is something he doesn't do.
