Germany’s top court reversed a decision^[1] by an appeals court, stating that there is no doubt that Facebook enjoys a dominant position in the market and also no doubt that Facebook abuses that position. The ruling is decisive and will most likely lead to stricter regulations governing how data are collected and used. The ruling also means that Facebook is on the losing end of an antitrust investigation, which brings up important questions regarding competition and data sharing across multiple platforms. Facebook has vowed to keep fighting, which may include appealing to the European Court of Justice.
