Your an Idiot
If you bought a sports car and wanted to fit new fat alloy wheels to it would you think it wrong if the manufacturer said you couldn't ? If you wanted to remap the ECU is it not the same as circumventing their software to make it go faster so how is it ok to do that ? If you own a knife and wanted to grind the end down and use it as a screwdriver is that ok? Finally if i owned a baseball bat i would seriously want to smack you round the head with it, he owns the console and if he wants to mess with it or throw it out of a 10 storey building wtf has it got to with Sony ?
