Unfortunately, I have to make a snide remark now. You didn't say "Who is Gaming biggest douche in the industry?", so now I have to give the honest and hurtful opinion.
My answer is the consumer, the customer, the FAN. Yes, I am placing the blame on the Unpleasable Fanbase because you didn't specify developers. Far more damaging than a moronic company is the literal thousand upon thousands of crossed messages from people who have NO IDEA what they really want, collectively.
EA is a dumbass. That's clear from the polls and anything I hear from threads here. But then, I'll also hear Activision and Valve and Steam and Bioware and yadda and so on and etc. You guys (and I speak in the broad 'you guys' sense, as in ALL FANS as one group) cause more harm just by being lots more who can do it.
