Seriously. Every form of entertainment has baked-in political assumptions, and that definitely includes #ttrpg . You might choose not to examine them, but this is an active choice on your part, and you don’t get to pretend that your entertainment is “free of politics”.
While I haven’t read those reviews, I think the implications of Steam removing reviews would be worse, since they would effectively be manipulating the user score of a game. User reviews are just that, user reviews. The score should indicate what users think, whatever their reasons may be for thinking it, no?
I don’t disagree with the rest of what you said though.
