What? There was literally nothing wrong with that message - including the final sentence. He's calling for everyone to self-reflect and have humility - only someone profoundly lacking in it could be bothered by a message like this
Is he? or is he venting at someone while accusing them of doing the same thing back.
If instead of "Is the problem actually the rust code causing you issue, or is the problem between the keyboard and the chair, and you just want to vent?"
he said "Is the problem actually the rust code causing you issue, or do you just want to vent?" it's perfectly acceptable. The snide insults are petty, unprofessional, and unnecessary.

I could just as easily say that anyone who doesn't see that should look in a mirror and see if the see an ass staring back at them, but I wouldn't. When I read this, I see someone blowing off steam and knowing they can get away with it. I respect linus, and as I've said elsewhere he's perfectly capable of handling himself without resorting to passive aggressive insults.
Of course it could have been written more diplomatically. Yet, many people clearly don't find it to be offensive/inappropriate - especially when viewed in the context of the entire post, which was very well written and diplomatic.
Moreover, I can very much see how those precise words could be said verbally, in person, in a completely disarming, effective manner - by using particular pacing, tone, gestures, a wink, etc. Whether Linus would do that is another matter - but your comment was talking about how it would be inappropriate anywhere.
