Germany's competition regulator has announced it will order Facebook to substantially restrict how it collects and combines data about its users unless they give explicit consent. The German watchdog’s decision follows concerns that users were unaware of the extent of Facebook's activities. In the future, the firm's various services, including WhatsApp and Instagram, will continue to be able to collect data, but they will not be able to combine it with data from a user's main account unless they consent. The ruling only applies in Germany, although is likely to influence other regulators.
