Information Security on Social Networks
Facebook representatives have also pointed out that users' privacy settings offer some protection: If you have set up your account to allow only your friends to see photos and other info, Facebook won't make that information public down the road. Whether the terms of service were clearer before or after the changes, what is clear now is that we are in uncharted territory. Communicating as a social network provider what is and isn't OK in a binding TOS agreement-and, as a user, understanding all of it-is complicated when the culture of and applications for social networking sites are changing every day.
But, still, that doesn't mean we should let Facebook off the hook, nor just blindly trust that the site won't misuse our information, as Zuckerberg seems to be implying we should in his post:
In reality, we wouldn't share your information in a way you wouldn't want. The trust you place in us as a safe place to share information is the most important part of what makes Facebook work. Our goal is to build great products and to communicate clearly to help people share more information in this trusted environment. We still have work to do to communicate more clearly about these issues, and our terms are one example of this. Our philosophy that people own their information and control who they share it with has remained constant. A lot of the language in our terms is overly formal and protective of the rights we need to provide this service to you. Over time we will continue to clarify our positions and make the terms simpler.
