Uk lawsuit: Apple's £2.7 Billion UK Lawsuit Over App

Apple is facing a £2.7 billion (roughly $3.5 billion) lawsuit in the UK over claims that its app tracking rules unfairly squeezed competitors while boosting Apple’s own advertising business.

The action was reportedly filed at the Competition Appeal Tribunal in London on behalf of millions of app users and consumers. Until now, the company’s App Tracking Transparency framework was widely seen as a privacy win for iPhone owners — this case argues it was also a quiet power grab.

Here’s what you need to know: the claim alleges Apple abused its dominant market position by forcing rival apps to ask permission before tracking users, while its own advertising services faced no comparable restriction.

The lawsuit is reportedly based on court filings, not yet officially confirmed by the company itself. Apple has consistently defended ATT as a user-first privacy measure.

Why the £2.7 Billion Claim Was Filed

The core allegation centres on timing and control. When Apple rolled out App Tracking Transparency with iOS 14.5 in 2021, every third-party app had to display a prompt asking users for permission to track them across other companies’ apps and websites.

Most users tapped “Ask App Not to Track.” Meta and other ad-dependent platforms publicly warned that the change would cost them billions in lost advertising revenue. Apple’s own advertising business, which runs inside the App Store, was not subject to the same opt-in requirement.

The claim reportedly filed in London argues that this asymmetry let Apple favour its own ads while competitors were throttled — a textbook abuse-of-dominance argument under competition law.

Because the case is brought on behalf of consumers rather than companies, it follows the UK’s collective proceedings model, similar to the opt-out class actions that have already cost major tech firms billions at the same tribunal.

How App Tracking Transparency Changed the Market

The before-and-after here is stark. Before 2021, advertisers could follow users across apps with device identifiers, building detailed profiles with no prompt at all.

After the rollout, opt-in rates collapsed, small developers lost a key monetisation tool, and Apple’s ad network grew in prominence. Whether you play mobile games after reading our Elden Ring Best Strength guide or browse shopping apps, the ads you see are shaped by these rules.

Before ATT (pre-2021)	After ATT (2021 onwards)
Cross-app tracking by default	Explicit user opt-in required
No prompts shown to users	Consent prompt on every app
Rival ad networks freely profiled	Rival ad revenue sharply reduced
Apple ads under same rules	Apple ads outside the prompt system
Regulators largely watching	Antitrust suits in multiple countries

That said, privacy advocates argue the prompts did exactly what Apple promised — returned control to users. The legal question is not whether ATT protects privacy, but whether Apple designed it to protect its own profits at the same time. Similar scrutiny is playing out in the EU under the Digital Markets Act and in the United States, so a loss in London would set a costly precedent.

What Happens Next at the Tribunal

£2.7 billion is on the line — and millions of consumers are reportedly automatically included unless they opt out.

The Competition Appeal Tribunal will first decide whether the case is certified to proceed as a collective claim. If it clears that hurdle, expect years of hearings, Apple appeals, and discovery documents that could expose how the company’s ad business really operates. A settlement remains possible, as has happened in prior UK tech cases.
If you use an iPhone and value the tracking prompts, this case argues you were right to tap “Ask Not to Track” — but says Apple should still pay for how it got you there. For now, no changes to your device are needed; the ruling that matters is still years away.
