I guess when he says "business reasons" he means "yeah, PC gamers are not dumb enough to pay for the last 5% of the game that we cut to release it later and make even more money".
BTW, Ubi, we are still waiting for the sales numbers?. Did the lack of DRM make a difference?. I guess it didn't, since if it had sold any less than expected at all, we would already have listened to the usual hysterics: "OMG!. PC gaming is dead!. Look, we took out the DRM and we only sold one copy!!!".
