I mean, that’s fair, and as was pointed out elsewhere Linus has sought help for his temper.

On the other hand, for all the talk of how “unprofessional” it was for him to behave this way, he did shepherd an OS kernel from a hobby project to the most popular OS on the planet (with the possible exception of Minix, apparently…)

I agree that polite directness might be better, bu IMHO the more common polite indirectness and avoidance of any hint of conflict is clearly worse.
