Overwatch 2 deserves to be criticized a lot. But this kind of review bombing is dangerous. Now it happened to a game a lot of people (rightfully) dislike. But what if it happens to another game that doesn't deserve it? Just because it shares different political views or ideologies? Or because it doesn't include an option for chinese language (it already happens)? Only kids can cheer at something like this, sorry.
I would disagree that public reviews like this are dangerous for games. This is basically the same way reddit or any other social media platform works. Aside from the fact that this is still advertising for OW2, even if it is negative, People will play what they want to play regardless of politics- a là harry Potter game or atomic hearts. Similarly, in the court of public opinion you are allowed to engage in whatever discourse you want, and embrace whatever ideas you'd like. That doesn't exempt you from the consequences of espousing ideas that are counter to the norm, but it does mean that you'd better be damn sure you mean what you say.
In other news, look at no man's sky or FF14! Public opinion is far from inflexible, if a dev is willing to put the time and effort into making something good out of a previously universally hated product.
