In testimony to Congress the week before last, Facebook CEO Mark Zuckerberg made a point of emphasizing that if you’re a Facebook user, you own your information. This is meant to reassure users, but it is more than a little misleading. “Your information” is what you personally have uploaded to Facebook. You do not own what other people have uploaded about you. That’s what has privacy advocates so concerned. It’s also why even therapists who don’t use Facebook should be worried about the client confidentiality risks that the company poses.
