The privacy cost of Facebook is too high. Even if you have "nothing to hide" today, sooner or later you will post something you wish you had not posted, or someone else will do it for you. Once data about you is out there, it is impossible to remove, and the only recourse is to wait for that information to become irrelevant or outdated (if ever). For example, some employers have been known to spy on their employees through Facebook. Others have been harmed when searching for jobs because of things they posted on FB or other antisocial media, often long ago.

Facebook should not have multiple high quality photos of 1/2 of the planet, their children, pets, friends and family, in addition to their real-time location obtained through the spyware companion app. Not even governments used to have this kind of insight into people's lives not so long ago, and it is certainly very alarming that a spyware/adtech firm now does.
