This is a massive dragnet, and it should concern you even if you've never heard of the app.
The Department of Justice has reportedly demanded that Apple and Google identify over 100,000 users of EZ Lynk, a vehicle software application. Not because all those users are suspected of crimes—but because the DOJ wants to investigate the company behind the app, and apparently user data is fair game for fishing expeditions now.
The background: EZ Lynk is based in the Cayman Islands and sells software that connects to vehicle diagnostic systems. The DOJ alleges the company violates the Clean Air Act by enabling "defeat devices"—tools that disable emissions controls. Think diesel trucks modified to "roll coal," belching black smoke because the owner bypassed EPA-mandated pollution limits.
That's illegal, and prosecuting the company makes sense if they're facilitating violations. But demanding personal information on 100,000+ users? That's where this crosses a line.
According to 9to5Mac, the DOJ sent subpoenas to Apple, Amazon, and Google in March and April, demanding "identities, addresses, and purchase histories" of every EZ Lynk user. Not a targeted list of suspects. Everyone who downloaded the app.
The justification, per the government, is that they want to interview witnesses about how the technology is used. But here's the thing: not every user of the app is breaking the law. EZ Lynk insists the software has legitimate uses—monitoring vehicle performance, running diagnostics, updating firmware. Some users might be mechanics. Some might be tuning enthusiasts who stay within legal limits. Some might have downloaded the app and never used it.
