Apple was hit with a 150 million euro ($162.4 million) fine by French antitrust regulators on Monday for abusing its dominant position in mobile app advertising on its devices via a privacy control tool.

France's Competition Authority has fined Apple €150 million ($162 million) for how it implemented its App Tracking Transparency (ATT) system. As reported by Reuters, the regulator found that Apple used its control over the iOS platform to unfairly disadvantage third-party developers and advertising companies while making it harder for users to opt out of tracking.

France’s antitrust watchdog fined Apple 150 million euros ($162 million) on Monday over a privacy feature that protects users from apps snooping on them because its introduction resulted in abuse of competition law.
