I would think that the transaction was perfectly legal, and that EA could in no way force people to pay for the games. I wouldn't however, be opposed to the idea that EA could revoke ownership of any subsequent free games obtained once the code had been successfully used, but it would be a PR nightmare if they did.
EA's only reasonable option is to eat the loss and write the cost down as a "lesson learned".
Isn't there precedence to this? For example, cases where Amazon priced something wrong and people bought at that price, even through the the price was almost certainly unintentional. I would think Amazon would have been obligated to honor the bad price until they discovered and changed it just like companies are on the hook for honoring mistakes in ads (although I think they might be covered by disclaimers these days).
