Okay, but in that PlayStation example you DIDN'T pay for the games, but still decided to 'do what you want'. How is that legitimate but attempting to prevent it not?
So logically, it isn't modding/unlocking the console itself that's illegitimate. But it can be used for certain illegitimate actions, yes (along with legitimate ones).
And these use-cases aren't only legitimate, in France they are even legal and in exchange we pay a tax whenever we buy a media storage device (Taxe sur la copie privée).
