I thought I would post the latest update to this situation. EA is now going to retroactively remove the online pass from their entire library of games. I guess coding requirements and updates means they will not be removing the prompt but will provide free passes for these games for anyone who wants them (they would probably remove it all together if Microsoft didn't charge for patches beyond the first one). That is kind of awesome of them.
