Apple finds itself in the crosshairs of a federal probe after the Department of Justice subpoenaed the company for data on users of the EZ Lynk vehicle‑modding app. The request seeks the name and address of every individual who downloaded the software, a pool exceeding 100,000 users. Under public scrutiny, Apple typically pushes back on overly broad demands, citing privacy and legal constraints.

EZ Lynk is under a civil suit accusing it of violating the Clean Air Act by selling devices that can disable emissions controls. Prosecutors argue that identifying downloaders will help locate witnesses for and build additional evidence. The company has signaled it expects Apple and Google to refuse the subpoena, echoing a 2019 case involving a gun‑scope app that was ten times smaller.

Privacy advocates warn the demand collides with Fourth Amendment protections, noting that download receipts are unencrypted but still constitute personal data. While Apple can comply with narrowly tailored orders, the breadth of this request may trigger a potential ongoing legal fight. Regardless of outcome, the episode spotlights the tension between law‑enforcement objectives and tech companies’ data‑privacy policies.
