“yeah, we know how to jailbrake your console, take that sony! Oh, but don’t worry, we won’t release this hack nor collaborate in any way to provide this feature to other people”

That this makes no sense is the whole point. The goal is to show how little sense this makes. It’s fine for you to break a digital lock yourself, but illegal for you to show others how to do it.

The goal isn’t to jailbreak the PS5. It’s to show that DMCA §1201 makes no sense.
