The bias on the site is really terrible. It's not always YComb itself so much, but all the valley stuff.

As with anything you have "the powerful people" who have opinions on what critiques are "fair", and will demand them communicated with perfect decorum.

Additionally, people are aware of how it will "look". In a way they don't care, but in reality there's always an appearance people prefer to keep.

Anyway actually break out some pointy critiques, and they'll get mad.
