When you agree to their new terms of service, you're waiving your right to sue via class action against Sony.

“Class Action Waiver. ANY DISPUTE RESOLUTION PROCEEDINGS, WHETHER IN ARBITRATION OR COURT, WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS OR REPRESENTATIVE ACTION OR AS A NAMED OR UNNAMED MEMBER IN A CLASS, CONSOLIDATED, REPRESENTATIVE OR PRIVATE ATTORNEY GENERAL ACTION, UNLESS BOTH YOU AND THE SONY ENTITY WITH WHICH YOU HAVE A DISPUTE SPECIFICALLY AGREE TO DO SO IN WRITING FOLLOWING INITIATION OF THE ARBITRATION. THIS PROVISION DOES NOT PRECLUDE YOUR PARTICIPATION AS A MEMBER IN A CLASS ACTION FILED ON OR BEFORE AUGUST 20, 2011.”

Don't fear. There is a way to not accept this new Terms of Service, but it requires you to cancel your PSN account.

On its own, this is pretty typical corporate positioning for many companies in this day in age. However, it is a bit of a slap to the face after the PSN network was compromised and personal account details were stolen.

Pretty damn lame. Cowardly is the word.
