I'm not sure it was "the right thing," though... would keeping my used copy and just dealing with not being able to export the songs have somehow been "the wrong thing?" It's a used copy of the game, not a stolen one. My whole point when I brought up perspective was that there really isn't a "good guy" and a "bad guy" here, just different views of an issue. Nobody's the villain.
I don't know if you guys know this, but if I were to buy a used Prius, Toyota wouldn't see a dime from me. They'd have already been paid for their product the first time it was sold. After that, the new owner is free to do with it whatever they want, including selling it to someone else. Nothing shady or dishonest or conspiratorial; just people doing business with other people.
