BKGaming: First... I have no idea who this is.
Second... I think it stupid for any company to cut ties with someones based solely on personal views unless those personal views are presented while said person is representing said company or product. I mean it sounds like his work with the game was done a long time ago, nor did the article say he was claiming to represent them or playing their game when this happened. What people believe and say on there own time is their business in my view. Would you remove someone from a game or movie from 5 - 10 years ago because they expressed controversial views today? Doubtful. The vast majority would not have known nor cared, but now because they removed him it will blow up into a bigger story than it would have been. But yea they have every right to do so if they wish.
Third... you can bury your head in the sand all day long, but issues such as immigration, nationalism, and the like are real issues that should be open to public conversation. Pretending these issues don't exist helps nobody. People would do well to put on their big boy pants and not get offended because someone shares a different ideology because these are real issues with real consequences.
Fourth... would I still buy the game? Yea. I see why they did it, I just don't really see it as necessary. In fact it will probably make the story bigger and could potentially negatively impact them worse than the original story about what he said. To many people and companies today want to be politically correct, and in the end they will only succeed in pissing off one side or the other by bowing to what they see as public perception.
EDIT: This is of course based solely on what the article stated... I don't personally know all that was involved.
It is just the way life is these days - you have to follow the directives of political correctness or you will be cut off, its that simple.
Noticed how many celebrities publicly support trump for example? There are some, but many don't have the courage to admit that, because its the pressure of political correctness.
You have the right to freedom of opinion, but with that you also have the right to lose your sponsors, you have the right to lose your endorsements, you have the right to be overlooked in your career, you have the right to be forgotten by society.
