Any time you think to yourself, "There ought to be a law!"

Just don't.

If you think about it, every law is a threat of violence. If you're not prepared to use violence, or at least force to some degree, to enforce it, you merely have a strong suggestion. Even if you just start off with handcuffs, if they escalate, you have to escalate, or let them go.

I think this is a useful heuristic for deciding whether something should be legislated: "is this worth using violence over?"

violence means very little in the context of corporations, since they're not people.

Do you know why corporations do what courts say (pay damages, clean up oil spills, etc.)? Because inside their scaly, corporate armor, they're made of squishy people.

And when countries like China make it a law mandating the existence of such backdoors in devices sold/manufactured in their country?
