If you had any idea the nefarious things they are doing with the information they collect about you, you'd probably have a different opinion. To be honest, non of us know for sure. Facebook won't tell us. We do know that they use facial recognition to build shadow profiles of people who don't even sign up. Appear in the background of a picture that someone you don't know posted on Facebook? Facebook uses the metadata in the photo to figure out where you were and at what time, and adds that to its vast collection of data on you. Play a game on Facebook? They use that data to develop a psychological profile of you. Yes, they do all of this to better target adds at you--adds that you see even if you're not logged on to Facebook. But this information is ripe for abuse as well and the fact is they don't tell us what they really do with it. Read their privacy notice. It's a joke. It essentially says they can do whatever they want with the data they collect.
