So much overreaction.
Hacks are inevitable and unavoidable. The important thing is in how the data that would inevitably be stolen was protected.
Valve hashed and salted their passwords. They encrypted their credit card databases.
Sony was fucking incompetent. It’s obvious that Valve knew exactly how to prepare for something like this.
Right now, no one has your passwords or credit card information. Cracking hashed/salted passwords would be next to impossible, and I doubt they used some amateurish credit card encryption.
