The censorship that offends me is the fact that it happened at all. And sure, they might have decided to go through with the changes internally on their own, but they're still changing things that I don't agree with that differ from the product I originally bought. It's their right to change the product they made, as is my right to stop using or endorsing their product to anyone I know because I am the consumer.
As for big band, police violence is horrible, yes. That's the whole point. He got beat to shreds and put in an iron lung, his whole story is grim and the art reflected that. Removing it makes it seem (to me) that it has become a race issue now rather than anything that had to do with his story. It also goes back to general censorship and my disagreement with it.
As for fanservice being what attracted players, the game's first tagline in the early trailers was literally "Hot 2d fighting." Most of the original characters were blatantly sexualized and had jiggle physics and revealing clothing as one of the first things you see. There was also the infamous Zone Filia porn flash that Tomar (the skullgirls announcer) was a voice in that endorsed the game at the very end. That flash had 300,000 views only 1 month (pic related) after it released, and you better believe there would have been people who went and bought the game after seeing that for the first time. All the changes might not affect the gameplay of the game, but not everyone plays this game for the gameplay. The artwork is handdrawn and lovely, and if that's one of the things I buy a game for, changing that would sour my opinion of it. At the end of the day, they changed something I don't agree with as a consumer, and that will directly result in me spending less money on it and negatively affecting the game overall.
