When we're dealing with someone who repeatedly have ignored advice, instructions and admonitions and continues to cause major breakage, then yes, it would be sugar-coating to write something similar to what you suggested.
The point is that the person in question was being rude and disrespectful by continuing to ignore the instructions he'd been given in the past, and repeatedly caused a lot of very real, very heartfelt anger from a lot of people over the time he wasted for them.
Pretending not to be angry over that is very much sugar-coating to me.
Now, there are nicer ways of being direct and expressing anger, but pretending there was no anger and no valid reasons to be angry would be flat out dishonest. And I really don't think the recipient in this case had any reason to expect any civility from Linus at this point, even if others might choose less direct language.
Exactly. And I'm not impressed with the way the "professionalism" police are so quick to condemn Torvald for one justifiably angry email while giving such a conspicuous pass to a sustained pattern of passively aggressive, measurably destructive, and flatly un-collegial behavior that is the true definition of unprofessional.
In other words, there's a pretty egregious double standard being applied here. In my experience, that typically favors the kinds of abusive personalities who have discovered some easily-exploited aspect of the social system to simultaneously provide cover for their own bad behavior while limiting their target's ability to retaliate.
If I were on a team stuck with this guy, and required by professional norms to bite my tongue, I can safely say I'd take supreme satisfaction in seeing such a nasty employee get this severely excoriated. And make no mistake, this isn't about "feedback" or "criticism". It's about driving the guy out of the shop in a way that provides a suitable catharsis for everyone who has had to put up with his actual and sustained unprofessionalism.
Of course, tf this were an arbitrary, unjustified, or otherwise baseless response, I could see how it would be hugely damaging to Torvald's authority, and the trust he relies on. But in a case like this, the opposite seems true. And if it puts others who present similar problems on notice, so much the better.
