I don't know what the big uproar is about. The fact is that we don't have a clue what this IW service is about, and 99% of the "disadvantages" that the dude in the video listed are all inferred, not based on fact (as far as I can tell). Sure, I do really hope that the PC game won't turn into a DLC-fiasco that the console market has turned into, but it's way too early to assume that Infinity Ward is going to do that. Seriously, you've decided to boycott the game because of this? Why not wait till more details come out and then make a decision?
That being said, the video does raise some good points regarding the dedicated servers. At this point all we can do is pray that IW won't mess things up. Then again, it will also be in IW's best interest to keep us PC gamers happy. So overall I think there's nothing to sweat about.
