Whilst I understand the argument that is made that you don't believe you are doing anything wrong I do agree to that, in reality its your hardware you can do with it as you please, however there is a another counter argument that the keys are part of the ps3 hard coded OS. This leads into a tricky area as to which parts of the machine you own as the software can be classed as theirs. Personally I don't think it is, they sold you the hardware and the hard coded OS as a package you can do with it as you please, they didn't lease it to you they sold you it as a package.
I still think staying anonymous is a great thing, nothing will change my view on that, if the information which at the moment only geo has to the best of our knowledge had been released without a name or an alias then Sony would be sitting their cursing and desperately trying to work out who it was but in the knowledge that they could no longer do a damn thing.
Sony have announced that they plan to prosecute everyone who's hacked a PS3.
For their next project they're going to piss in the ocean to warm it up.
