18 years later and still waiting for the management/programmers behind Sony's trojan rootkit to face criminal charges for hundreds of thousands if not millions of violations of the CFAA.
It's not a backdoor. if anything you're the one renting Sony's server space.

That's what would happen to me if I sold you a piece of software and then used a backdoor to delete data of your computer
