Having your purchase taken away is not punishment. It's done because it's not actually yours, it still belongs to the person it was stolen from. It's a negative for the person who made the purchase, but that's just an unfortunate side effect. Unknowingly buying stolen property is not legally wrong. The typical law punishing receiving stolen property requires the receiver to know that it is stolen. Otherwise you're innocent of any wrongdoing, you just got ripped off.

If unknowingly using a stolen gift card just meant you lost your money, nobody would be complaining about Apple's behavior here. The issue is that they didn't just lose their money, they also got their account locked, which locks up a lot of stuff completely unrelated to gift cards.
