Just because they can, doesn't mean they should.

I'm fairly accepting that every android app asks for "permission to read ..." permissions, but I don't want them to be so proud of this that they present their information back to me.

That's what is so creepy about Facebook, they've lost sense of what is normal, so they don't hesitate to show off how much they know.

I'm sure Google knows a lot more about me, but they have the sense not to parade that fact back to me unless I specifically ask.
