"German consumer organizations are suing Facebook because the social network keeps sharing personal data with third-party app makers without getting explicit consent from users. Third party apps often want access to a users' chat as well as information about friends, personal contact information and the ability to post on a user's Facebook wall. But instead of asking users for permission, the apps available through Facebook's App Center just grant themselves access to the data, the Federation of German Consumer Organizations (VZBV), said on Thursday. ... In the past, Facebook asked for user consent by showing a pop-up window that warned data was shared with third-parties, and a user had the choice to click on allow or not allow. But when the App Center was introduced that changed, said Michaela Zinke, policy officer at the VZBV. 'I'm very confused why Facebook changed it,' she said, adding that before Facebook complied with German law and now doesn't anymore."
