Given the downmods each of us got in the pile, it seems this is a contentious issue.
Personally, I disagree with your assessment, but that said, I am aware that one person's fair assessment followed by a harsher and unequivocal reply if the assessment is rejected, may easily be seen by another as undue abuse.
I make no apologies for the list, because it reminds me exactly of a typical USAF flightline. Doing something dumb or misguided will get you a direct and to-the-point talking-to; first logical and fair, but increasingly harsher if you continue to resist even listening.
The reasons why are different but just as serious: in the kernel, screw-ups in design and/or direction can eventually destroy the kernel's usefulness and flexibility. On the flightline, screwups in procedure or behavior will eventually get you killed.
The harshness against any whining and/or backtalk in either case is not just someone being a turd - it's a reminder that there are reasons for things being as they are, and any proposed changes had better have a damned good reason up-front.
HTH a little.
