[Question] Is the game design/​art maxim more generalizable to criticism/​praise itself?

For those who don’t know, the maxim of criticism that game designers/​art people use in their responses to criticism is roughly the following:

“If you get a negative reaction on it’s own, that’s evidence that there’s a problem.”

“If customers give any reasons why or solutions to the problem, ignore that criticism.”

Is this generally true of criticism against anything, and if so, why do you think this happens?
