Microsoft is the least deserving to stay in the gaming industry. They have been guilty of numerous horrible practices such as not allowing self-publication, enforcing DRM with EA, moneyhatting, and forcing Kinect. While MS has changed much of their policies, the fact that MS used to be so hardline on their DRM and anti-indie policies is hard to ignore and not easily forgiven.
Nintendo isn't doing too hot either, but at least they're doing well with the 3DS.
