I don't think there was any intent to say he must be a douche. I suggest you read carefully what was written. He just says that the author is hawking 'make games with gamemaker' but in reality, the author may have gotten some money, but the real moneymaker is in writing libraries and using your platform as a way to sell other games. The way it was written was certainly not passing judgement on anyone.
