I agree, but what I disagree with is the idea that everyone must be prevented from freely installing software on their own devices to make sure unskilled people cannot be tricked into doing it.

I don't really understand why a well designed sandbox and permissions system doesn't solve the problem.

Well cars kill people, granny using the password “password” does not. We can’t prevent all levels of stupidity and carelessness.

If people want to have dumb passwords and download malware, then so be it. You think they can’t do that today with the google play store? Of course they can. Most malware on android comes from the Google play store.

Maybe a drivers license should be needed to have a phone.
