In recent days, Facebook has spoken out against the NSA's data collection, with Facebook General Counsel Colin Smith saying in early September, “The actions and statements of the US government have not adequately addressed the concerns of people around the world about whether their information is safe and secure with Internet companies.”

However, it's now Facebook itself that is drawing the criticisms of privacy groups, who aren't too happy with the social media site's changing data use policies.

Officials of six privacy groups, including the Electronic Privacy Information Center, petitioned the Federal Trade Commission (FTC) on Sept. 4 attempting to block Facebook from changing its data use policies. According to Bloomberg, the groups are concerned with how the company uses private user information for advertising.
