From my insider source, I'm told that permissions will change significantly in the near future.

Just FYI: a lot of other apps also utilize the same permission. Just an aside but Google also has the authority to whitelist certain applications for these permissions - meaning they can enable certain invasive permissions without asking the users.

We shouldn't just vilify Facebook. It was how the privacy framework was designed for Android that's the issue. This will change in the next upcoming versions.
