This is still pirating. The fact that you don't share the cracked media doesn't change the fact that you violated the T&Cs. And I'm pretty sure they could sue you for piracy.
In the US, I don't think they could (but it may depend on the details of how you did it). They could sue you for contract violation, but would they? There's no upside for them to do so.
You have a right for a private copy in Germany too, but you are not allowed to use software who can "delete security mechanisms"...that's why it is such a BS law.
