This is a stupid argument if they really have it; the game still requires dedicated servers on the one hand, and as many people in this thread already commented, it doesn't make for a good gaming experience. If they did dedicated servers and made sure the experience is polished, more people would play and keep playing, and they'd be able to make more money from in-game purchases and the like.
