...this is not at all Linus going nuclear. I don't see any threats or 'yelling'. He could have been more diplomatic, and I think Linus was actually trying to be. Diplomacy isn't his strongest suit. I don't think the first comment in his reply was necessarily appropriate, because it was directed at the person rather than the problem. I can also understand not wanting to mince words and establish a very firm boundary so it doesn't become a perennial conversation.
