I think not supporting a company you don't like is a perfectly legitimate reason. It doesn't make you the South Park WoW-nerd to not want to give money to a company you dislike. As we've seen with XB1, speaking with your dollars is really the ONLY way to make a point.
Yes, but the reasoning behind the dislike can vary. This is why the "Worst Company in America" awards are bullshit.
True, but not buying products from a company doesn't mean you voted for them in that poll. I don't buy Chick-Fil-A because I don't support them, but I'm not about to go and report them to the BBB as an affront to business.
I'm not even referring to their business practices-- someone could really just take issue with their games and how they make them now. I could see that being a totally viable reason.
