This all sounds like a bunch of complaining for nothing. Now, I don't play games on computers but I know what people do with the whole dedicated servers. Get over and move on. Infinity Ward won't be affected by this. The game will still be incredibly successful, hence is why they are sticking to their guns.
You don't play on computers, and are therefore clueless about the infinitely superior flexibility afforded by them.
If Infinity Ward said "we decided to charge PC gamers $10 more for an inferior, dumbed down, gimped port of our console game", I would have no issue.
