I think both of these positions are important for coercing Sony. If everyone who was upset left permanently and kept their bad reviews, Sony would have no incentive to backtrack their next boneheaded decision. But it's also true that if everyone jumps back in as if nothing happens, they have no incentive to avoid excessive greed in the future.

Most of the players will come back, and so Sony will be rewarded for compliance. But some players will be permanently alienated, and those permanently lost profits will be a reminder of what happens when you try to screw your players over.
