The core of the complaint appears to be that Facebook now treats users' names, profile photos, lists of friends, pages they are fans of, gender, geographic regions and networks to which they belong as "publicly available information". Those categories of user data are no longer subject to users' privacy settings.
In short, users can't stop Facebook distributing that information about them.
The settings came into effect in the last few days. EPIC and nine other privacy and consumer groups argue that Facebook's new privacy settings "violate user expectations" and "diminish user privacy."
The wording of the complaint includes an assertion that Facebook leads users "to believe falsely that they have full control over the use of their information," and further that is "undermining the ability of users to avail themselves of the privacy protections promised by the company."
The complaint also states: "Facebook's changes to users' privacy settings and associated policies regarding application developers in fact eliminate the universal one-click option for opting out of Facebook Platform and Facebook Connect, and replaces it with a less comprehensive option that requires users to provide application developers with personal information that users could previously prevent application developers from accessing."
