Facebook's photosharing site Instagram backtracked Tuesday on its new user privacy policy that would have allowed the site to sell users' photos to advertising agencies.

"I'm writing this today to let you know we're listening and to commit to you that we will be doing more to answer your questions, fix any mistakes, and eliminate the confusion....

"To be clear: it is not our intention to sell your photos. We are working on updated language in the terms to make sure this is clear."

While this update may be comforting to Instagram's users (at least for now) the question remains: Why does Facebook continue to shoot itself in the foot, so to speak, when it comes to privacy issues?
