I'm assuming you would do this out of a political reason, or as a very technical and privacy aware user.
But you are providing an alibi for malicious users who, for example, might try to brute force logins from unidentified devices.
That would be one reason aside from the law. You are essentially positioning yourself on the same side as intruders.
aka guilty until proven innocent.
are you for real? no, its the government telling regular people that simply wants to control their device that THEY are criminals and on same side as intruders.
You should personally immediately return any computing device where you have control, this line of reasoning is insane
You're claiming that the only legitimate use of rooting is criminal activity, which is not true. Your argument is based on a faulty premise in my eyes.
