Some of the other places I have seen we aren't too worried about origin (before you stop me, no, I do not claim to speak for the entire internet). Scanning the registry is still no different from what some other services (some not even game related) do, and I'm pretty sure the escapist has our IP addresses too, and don't even get me started on google. I still think the origin complaints are mainly from people who have to look for some problem with Battlefield, but that comes from the perspective of a self-confessed battlefield fanboy.
Other than being a (possible, Never used it fully, and when it has been running in background I don't seem to notice) resource hog and another advertisement crammer I really do not see a problem with it. Not to say that I love it and that all games should be sold on it, I still prefer steam for that, but I still think its just a case of looking for a new Gaming Emmanuel Goldstein after MW hate has gone stale (I still plan to buy MW3 despite the fact that I know the Frustration in MP is going to be immense as the last one I got[MW2])
