It's not "file permissions", it's the permissions that the Android app is asking for, and you're granting it, at install time.

I've mentioned this here before: look at something like the weather channel app on Amazon's app store, which requests an astonishing array of permissions, including the permission to dial out silently without your interaction.

The Android apps, like Facebook apps, are overreaching, and training users to accept the incursion in order to use well known apps, leaving them more likely to accept the same from obscure apps.
