The reality of the situation is that most of the company's sales comes from the Chinese market, which is the reason why there are so many negative reviews. You need ownership of the game to post a Steam review. This situation could be alleviated if other people buy the game because it has English translations.

The reason for anger I've heard from Chinese gamers is that they turned this issue political whereas in the past games didn't involve politics and they're pissed that their apolitical space has been invaded. As well, streaming the game has gotten Chinese game-streamers in trouble or having to take down their streams/videos.
