Facebook has succeeded in blocking a pioneering order by Germany’s Federal Cartel Office earlier this year that would have banned it from combining data on users across its own suite of social platforms — Facebook, Instagram and WhatsApp — without their consent.

Pioneering because the antitrust regulator had liaised with EU privacy authorities during a long-running investigation of Facebook’s data-gathering activities — leading it to conclude that Facebook’s conduct in the German market where it also deemed it to hold a monopoly position amounted to “exploitative abuse”.
