The court alleges the two property rights the plaintiff argued Sony deprived him of are insufficient: (1) the loss of the right to pursue class action claims outside of arbitration against Sony; and (2) the loss of access to the PlayStation Network.
They're stating that losing access to the PSN is not harmful, it's a choice. Kind of like how you can choose to go into McDonald's after they decide you can't bring in your favorite hat. Er... that's a bad metaphor. My apologies.
Either way, the court case is finally... closed. You can read more about the decision here. On the plus side, it wasn't totally unknown about these changes and you do have a choice. Sort of.
