This question already has an answer here:
I don't understand, why some programs are requesting some permissions, especially concerning my privacy.
So I want not to grant them or revoke after granting.
I don't care if application will crash. I expect, that polite application will never access my private data without first asking explicitly. Since I won't permit this, then polite application will never crash. And mutual, if application will crash, then it is not polite and should be uninstalled.
