Exactly, I don't see this any more privacy invasive than Google Now.
It really boils down to how much you trust the company/app.

Google also use that data to provide a service (automatically call the navigation app to came back home at night or just give you a reminder on places you go every week). I doon't think facebook will give any kind of service other than keep my friens updated about whatever I do and wherever I go and this is frightening (not the fact that a big company has this data but the fact that everyone will know it)
It's PAINFULLY EASY to mark that information private, and to go into the Platform settings and make sure your friends "cannot bring your information with them into apps and websites".
It's two screens and takes about thirty seconds for you to control your Facebook and how much data leaves it.
Seriously guys, don't blame Facebook for your incompetence with their privacy settings.
