LOL, you don't even have to go that far to point out the flaws of physics in halflife 2. Stuff moves around like they're in some sort of moon gravity. The CoD fans don't give a crap if the office chair rollers don't have physics, or that the collision for the doors on the fire extinguisher boxes have weird collision problems. They aren't playing it for that. Do I think CoD sucks? Yeah, that's why I didn't buy it. But I hardly need to nitpick a minor aspect of the game that most of it's fans couldn't care less about and even less who actually notice it's even there with issues. Yes, the game is the FPS equivalent of Madden, I don't play Madden either. Pretty much the only physics anyone cares about in CoD, is for grenades, that's it. The office chair not rolling around isn't going to affect gameplay for 99% of the players.
