Arguing against the conventional wisdom, Bruce Schneier writes that young people care about it:
Privacy is about control. When your health records are sold to a pharmaceutical company without your permission; when a social networking site changes your privacy settings to make what used to be visible only to your friends visible to everyone; when the NSA eavesdrops on everyone's e-mail conversations–your loss of control over that information is the issue. We may not mind sharing our personal lives and thoughts, but we want to control how, where and with whom. A privacy failure is a control failure.
