this isn't true . Let us take as an example the story of graph_chokolo. If he had never made public on his blog that SONY had opened a legal inquiry against him, we wouldn't have known anything about it .The same for all Hackers work / contribute on PS3 and other console .
I believe and soon I can prove that this story is not just a "rumor" , but is real . It's been a while that he spoke ...
Wait a few days and there will be major developments on this matter ..
A few weeks ago were leaked important documents and files about PS4 ( nintendo doesn't know anything ) and they are resold to the highest bidder !
And I became aware that happens the same thing about PS3 Confidential files , like SDK and other things .
