The idea is to make it so convoluted that normal users won't go through with this, if a friend tells them this is how to install an app that actually acts in the interest of the device owner. Either that, or it becomes so normal that most people will just do it without a thought, and then it fails to protect anyone from anything.

I like the cooldown as a protection, though. But given what else you can do with an unlocked phone without a cooldown, it seems overkill.
