Apple has been sued for $2.7 billion over App Tracking Transparency rules

The ATT lawsuit is the logical endpoint of a narrative Apple has carefully constructed since 2021: privacy as a product feature, and then privacy as a competitive moat. When ATT launched, it was genuinely disruptive—apps like Facebook and Snap saw measurable revenue dips as opt-in rates for tracking cratered. The policy forced a fundamental rethinking of attribution and ad targeting across the mobile ecosystem. But the question that has always lingered, and which this £2.7 billion claim crystallizes, is whether Apple built a wall around its own garden while calling it a public park. The plaintiffs' core argument—that Apple exempts itself from the same tracking restrictions it imposes on others—is not new, but it's gaining legal traction. Apple's own Search Ads operate on the App Store without the same ATT friction, and its advertising business has grown substantially since ATT's rollout. The company has argued that its first-party data collection is distinct because it doesn't require cross-app tracking, but critics counter that the distinction is semantic, not substantive. From a technical standpoint, Apple's advantage is structural: it owns the OS, the app store, and the ad platform, so it can achieve attribution through OS-level signals that third parties simply cannot access. What makes this case interesting is not just the monetary claim but the precedent it could set. If courts accept the argument that ATT is anticompetitive in its application, Apple may be forced to either relax restrictions on third parties or impose them equally on itself. The former would dilute its privacy narrative; the latter would undermine a growing revenue stream. Either outcome reshapes the mobile advertising landscape. The broader lesson for technologists is that privacy policies are never purely technical decisions—they are market-shaping instruments, and the companies that design them will always be tempted to design them to their own advantage. As with similar cases in Germany and France, the outcome is uncertain, but the direction is clear: regulators and plaintiffs are no longer taking Apple's privacy claims at face value. They are asking who benefits, and the answer increasingly appears to be Apple's balance sheet.
