I think this is just a symptom of a greater issue. Many of us assume that when we post something on the internet (facebook) it should be private. The reality is that you are handing your information over to another entity, and you are doing so willingly. That entity has vast resources and the ability to change the terms of service and rules at will.

If you just have the mindset that anything you share on facebook will be posted on a billboard in Times Square, you can know for sure that you are getting the privacy you want.
