Under the shared responsibility model, such veto makes sense. Just because the end-user (the app has no way to determine if it was a thief or a spy or a monkey or the actual device owner) approves of an action doesn't mean the OS and the app
have to grant authorization.
I can see how such a setup is hostile to power users, but then Android is used by 50% of all humanity, and your guess is as good as mine as to just how many want "sudo make me a sandwich" level of control.
