You just used words that you think are criminal offences,
§§ 240, 303 StGB.
Yes I know that’s German law. I don’t know US law. But I bet if I sold you a fridge and three days later came into your house and said “sign this or I’ll destroy the fridge” that’s a crime in the US. “Computer sabotage” is the rough equivalent of “trespass” in this example, you still have property damage and coercion even if computer sabotage doesn’t apply for some reason.
