"" I still don't understand what legal grounds sony is using for this... I always figured when you bought something what you did with it was your own business "
The guy did not hack for his own purposes, he also included re-distribution of copy write material. This is where he is wrong. If someone buys a game, then hacks it for himself at home, nobody would ever know about it, but as soon as you go ONLINE anyplace with said material, you have now broken the law, this is where he is wrong. re-distribution of copy writed items is illegal, unless you have owner consent to do such actions. Companies make products so there employees can earn a living, and stay in business to keep going. Every business works in this fashion, so stealing work from people that never hurt anyone just trying to keep their jobs in tough times is wrong. Not just Sony they have many partner companies that help distribute content, so all those persons work is now effected as well since less money means someone will get laid off. Hurting people that are just trying to have a job is wrong, and hackers dont understand that.
