Apple’s latest system update, which includes a new enhanced privacy setting, could unfairly exclude companies from advertising revenues while bolstering its own ad revenues and market dominance, according to an antitrust complaint filed at Germany’s competition agency this week.

The German Advertising Federation (ZAW) filed the complaint at the German Federal Cartel Office (Bundeskartellamt) on behalf of the nine industry associations and companies that it represents, which include social media giant Facebook and German publisher Axel Springer.
