I agree with you in theory, but in practice half the population are never going to become security experts and it's impractical to force them to learn through necessity. If a hacker can get root on your smartphone, they can probably get access to your bank account (and the 2FA), your email, your private/intimate photos, your medical issues, your sexual secrets, and so on. A smartphone is far higher stakes than anything else which has come before it. To be clear, I think our right to have a smartphone we control is an absolute. It's extremely important. I would march on the street to protect that right. But I'm equally protective of my right to have a smartphone I cannot control no matter what button I press. I'm glad for devices like the iPhone where the manufacturer works damn hard to make sure that it's always under the manufacturer's control.
