Is the same game you were posting memes about yesterday, suddenly bad? No longer having fun?
Who do you think you are going to hurt between the less-than-30-person studio or the multinational behemoth?
Are you going to refund the game today then buy it again tomorrow when the change is reverted? You might be hurting the developer even more.
IMO Steam reviews should completely disappear as it's no longer an useful gaugfe of a game quality. Hell, I see people leave negative reviews to co-op games such as "I hAvE No fRiEnDs tO PlAy iT WiTh lOl." Are you stupid?
Besides, buy the game, test it and if you don't like refund it.
