Right but granny is not a child, she is kind of the opposite of a child.

You're essentially saying we should child proof the entire world, right. Appeal to the lowest common denominator and DO NOT offer back doors. But that's a plainly ridiculous notion and everyone knows it. This argument only works on smartphones right now because it's the status-quo. As soon as you extend it to literally any other domain, it immediately crumbles and falls between your fingers.

Yes, there IS a certain level of protection that is acceptable at all times. But that level is absolutely not "maximum protection, no other options sorry". Which is what Apple is trying to do. This really is "no sale of knives" type stuff. That sounds ridiculous, right? Because it is, and we let Apple get away with murder.

The failure modes are often quite similar - cognitive/motor issues and lack of experience with the tools offered.

Back doors accessible by scammers are bad for the same reasons back doors accessible by governments are.

Apple's more like a shop that declines to sell knives. There are other shops that will sell you one.
