U.S. DOJ demands Apple and Google unmask over 100k users of car-tinkering app

The U.S. Department of Justice has issued subpoenas to Apple, Google, Amazon, and Walmart seeking personal data on potentially over 100,000 users of EZ Lynk's Auto Agent app, a tool accused of allowing drivers to bypass emissions controls on diesel vehicles in violation of the Clean Air Act. EZ Lynk denies the allegations and argues the demands constitute Fourth Amendment overreach, while privacy advocates warn that most users may face unintended legal exposure for downloading an app marketed for legitimate vehicle diagnostics and tuning. Apple and Google are reportedly preparing to challenge the subpoenas, with the case's outcome potentially setting important precedents for how government agencies can access app user data.
