Except you dont HAVE to buy those products in order to get into the beta, for example I preordered the game itself and that gives me beta access. So while its a daft marketing idea, his video is factually incorrect when he rants on that you MUST buy those products in order to get beta. Not hugely surprising though as looking through his video history , almost every single video he has done is slating one game company or another, in fact he seems to have virtually no videos that say anything positive about gaming at all. Makes you wonder why he bothers to game !
Hell, you even have a chance to get beta access without pre-ordering the game too (pre-ordering simply guarantees beta access)
