EA Sports Disabling Multiplayer on Games Bought Used

I don't know why I am still amazed at the way game companies keep finding new ways to nickel and dime customers, but this latest effort from EA is simply baffling. Try to follow with me the new lifecycle of a game purchased new and then used:

1. Gamer 1 buys new EA Sports game. Game comes with one-time registration code called an Online Pass that allows Gamer 1 to access assorted online modes including multiplayer.
2. Gamer 1 sells game to, say, GameStop.
3. Gamer 2 buys used game from GameStop and has the option to pay an additional $10 to EA for an Online Pass to access various online features. This version of the pass, however, does not allow even basic multiplayer online play.

So... Even with the extra fee paid to EA, which in theory should make up for some of the revenue going to GameStop instead of the publisher when a title sells used, gamers still cannot access the full game? If this is the way EA wants to go, why not just add say another $5 fee to enable multiplayer online play? I am finding it difficult to believe that EA is truly putting its foot down when it comes to online multiplayer access instead of just using the opportunity to charge a little more (on top of the little more they are already charging for "features" that don't include the only one I care about online - multiplayer). Based on the popularity of EA Sports games, I'd say this move will be initially financially successful, but if I were EA I'd be wary of pirates and defectors to other sports publishers.
