I have nothing against your mom, who I don't know, and I'm sure she's a fine person, but nonetheless, your mom is your problem. Why does your mom become my problem. Why must my freedom be restricted to protect your mom from herself on the computer?

Your mom is presumably able to drive a car, which is a killing machine in the wrong hands. Your mom can drink alcohol, smoke cigarettes, buy a gun, use a chainsaw. All of these activities are infinitely more dangerous than using a smartphone. OS lockdown in completely unjustified in comparison. It's a vast overreaction by "helicopter children".
