Bullshit, it’s just him doing a silly voice for a few characters, how does that make them somehow represent his viewpoints?

This is 1) extremely disappointing and 2) not surprising. They absolutely have the right to change their own content as they see fit, though I disagree wholeheartedly with the reasoning. I would still buy the game though, because it's best to divorce content from creators mostly. If I didn't buy anything from people whose views I didn't agree with, I'd only get to listen to Kid Rock.
