Germany’s national competition regulator has ordered Facebook to stop combining user data from different sources without voluntary consent. The order applies to data collected by Facebook-owned platforms like WhatsApp and Instagram, but also third-party sources that Facebook uses to flesh out its advertising profiles, including those of non-users.
The Bundeskartellamt, or Federal Cartel Office (FCO), has given Facebook one month to appeal the landmark decision, which comes after a three-year investigation. If the appeal fails, the tech company will have to ensure these data sources are not combined without consent within the next four months. Although the ruling only applies within Germany, the decision could influence regulators in other countries.
