Apple faces $2.7B lawsuit over app tracking rules in London

Apple is defending itself against a $2.7 billion lawsuit filed Thursday at London's Competition Appeal Tribunal, brought on behalf of app developers who say the company has weaponized its control over the iPhone to tilt the playing field in its own favor. The case centers on Apple's App Tracking Transparency feature, introduced in 2021 as a privacy tool that lets users decide whether apps can monitor their behavior across the internet. But the developers suing argue that Apple applied the rule selectively—imposing strict limits on what third-party apps could do while exempting its own advertising business from the same constraints, handing itself an unfair advantage in a market where tracking data is currency.

Ann Pope, who spent years as a senior competition official in Britain before taking on this case, is leading the charge. She frames the lawsuit not as a technical dispute but as a matter of fairness and power. "Apple acts as a gatekeeper," she said in a statement, "and the rules it applies are not the same for everyone." The harm, she argues, has been substantial and measurable—British companies that depend on Apple's platform to reach customers have lost money because they cannot do what Apple's own services are permitted to do. The lawsuit seeks compensation for those losses and a declaration that Apple's practices violate competition law.

Apple's response is straightforward: the company says App Tracking Transparency was built to serve users, not to disadvantage competitors. In a statement, Apple maintained that it operates under the same rules as all developers and that the feature simply gives people "a simple way to control whether apps have permission to track their activity." The company does not dispute that it created the tool or that it applies to third parties; it disputes the characterization that the application is unfair.

This London case is not Apple's first brush with regulators over the same feature. In Germany, Apple faced accusations from the country's competition authority that it was abusing market dominance. Meta, which owns Facebook and Instagram, joined publishers, advertisers, and app developers in complaining that Apple's tracking restrictions were strangling business models built on targeted advertising. Last month, Apple agreed to modify its rules in Germany, a settlement that suggests the company sees real legal and political risk in defending the current system unchanged. Similar investigations are underway in France, Italy, Poland, and elsewhere across Europe, each one probing whether Apple's privacy tool is actually a competitive weapon dressed in the language of user protection.

The London lawsuit represents a shift in how this dispute is being fought. Rather than regulators investigating Apple's conduct, app developers themselves are now seeking damages through the courts, claiming they have suffered direct financial harm. If successful, the case could establish that Apple's gatekeeping power—its ability to decide which apps reach iPhone users and under what terms—can be challenged not just by governments but by the businesses that depend on its platform. For Apple, the $2.7 billion figure is not trivial, but the precedent may matter more: a ruling against the company could open the door to similar lawsuits across Europe and potentially reshape how Apple manages its App Store and advertising business.
