Showing some prejudice there are we? It's not as if going to a website to get the code was particularly difficult in the old days. And the novelty does wear off after the first time anyway.
Was a nice joke in 2004 that this website really existed. It's 2012 now. Nuff said.
Btw.: I don't know where this pc elitism over difficulty comes from.
Console games are usually more difficult than pc games.
No mouse, no keyboard, no configuration options for the controls, quicksaving wherever you want to is an exception and no cheating as cheats prevent achievements/trophies and drop down consoles to enter them are only available in pc games.
PC games where always easier to beat and this hasn't changed to this very day.
And Call of Duty has it's roots on pc....
