Isn't it fantastic how a company can sue someone for using something that he bought in a way that was not intended by the company? This make 'ownership' kind of a funny thing since Sony still has rights on a product even if it does not own it any more (you bought it!).
I know that some other countries (e.g. Germany) allow anyone to do whatever he likes with something he bought as long as he does not re-sell it. But if he bought it, it belongs to him, and he is free to do with it whatever he wants--be that using it as intended, destroying it, or hacking it.
What if Sony would declare it illegal to destroy your Play Station? Would they be able to sue you for throwing it out a window? Would they be able to sue you for indadvertedly breaking it during a power surge?
Seriously, this is very close to what is happening to Hotz right now. US law is fucked up!
