I think you two may have a confusion of terms. I'm just guessing here, but I suspect the complaining they are referring to is the zero content anger spew some people think is appropriate, not critique.

I see it a lot in small communities centered around open source games. It is easy for some one to vent their anger in a useless fashion (can we agree that pr teams calling it passion is a euphemism they use to avoid insulting people giving them money?), and comparatively difficult and rare for people to put their experience into relatable terms or to criticize a change as it pertains to the project's goals.
