As far as I'm concerned they do. But my opinion doesn't decide the rating of a game any more than yours that's it's supposedly a better game than bad rats.
It's a product of everyone who votes giving their opinion, and the entire steam userbase has come to the consensus that Overwatch 2 is a particularly egregious example of it.
It cannot possibly be a review bomb when the reviews are legitimate opinions based on what the game is.
