As I recall, the guy that went to prison just did a temporary suspension of the emission systems so the truck driver could keep going until he could get it fixed. The modern emissions on diesel big rigs derate the engine when a problem arises, and can be a maintenance nightmare that even dealer mechanics have trouble fixing. And it looks like this app deals with regular pickups, but just grabbing all the downloaders and purchasers is a gross overreach, and how the government views your privacy while also a violation of the 4th amendment. And them asking for a secret backdoor into the app shows just how far the government is moving to violate your privacy so it can get all the data it desires. And just think about how modern cars are spyware, and what backdoors might exist in the car’s firmware? And they’re so sneaky, they’ll void your warranty if you knock your vehicle offline and it can’t receive software updates. Perhaps you could try and follow updates and temporarily put your vehicle back online, though it might upload data, but I’m sure it has limited storage. The federal bureaucracy is diabolical.<\/p>\n\n\n\n

The DOJ’s legal theory is that clicking “I Agree” on a standard app privacy policy means you volunteered to be identified by the federal government.<\/h5>\n\n\n\n

By Christina Maas<\/p>\n\n\n\n

In November 2025, President Trump pardoned Troy Lake, a Wyoming diesel mechanic who spent seven months in federal prison for disabling emissions controls on 344 heavy-duty trucks.<\/p>\n\n\n\n

Senator Cynthia Lummis pushed for the pardon. She called the prosecution \u201cweaponized.\u201d<\/p>\n\n\n\n

Two months later, the DOJ announced it would stop pursuing criminal charges for the exact thing Lake went to prison for. \u201cDOJ is committed to sound enforcement principles, efficient use of government resources, and avoiding overcriminalization of federal environmental law,\u201d the department said.<\/p>\n\n\n\n

Emissions tampering, in other words, was no longer worth the government\u2019s time.<\/p>\n\n\n\n

Two months after that, the DOJ sent subpoenas to Apple, Google, Amazon, and Walmart, demanding<\/a> the names, home addresses, phone numbers, and complete purchase histories of more than 100,000 people who downloaded a diesel truck tuning app called EZ Lynk Auto Agent.<\/p>\n\n\n\n

The government that just finished explaining it had better things to do than prosecute diesel tuners apparently has nothing better to do than build a database of them.<\/p>\n\n\n\n

What You Get for Clicking \u201cI Agree\u201d<\/h2>\n\n\n\n

EZ Lynk Auto Agent plugs into your truck\u2019s diagnostic port and lets you interact with engine software through your phone. Shop technicians use it for diagnostics, fleet managers use it to monitor electronic logging devices, performance guys use it to adjust engine settings, and some people use it to delete emissions controls, which was illegal under the Clean Air Act.<\/p>\n\n\n\n

The subpoenas went out in March and April 2026 to four companies. Apple and Google for app download records. Amazon and Walmart for names and addresses of hardware buyers. In a joint letter filed May 5 in federal court in Manhattan, DOJ lawyers explained they needed this to \u201cinterview witnesses about their use of EZ Lynk\u2019s technology.\u201d<\/p>\n\n\n\n

Interviewing witnesses, by the DOJ\u2019s definition, requires identifying every single person who ever installed the app. The technician in Ohio who uses it for diagnostics, the fleet manager in Texas tracking electronic logs, and the guy in Montana who downloaded it in 2018 and never opened it are all, apparently, witnesses the government needs to speak with.<\/p>\n\n\n\n

EZ Lynk\u2019s lawyers, from Baker Botts and Bourelly, George + Brodey, asked the question that should be obvious. \u201cThese requests for potentially hundreds of thousands of people\u2019s PII go well beyond the needs of this case and create serious privacy concerns,\u201d they wrote. \u201cInvestigating this claim does not require identifying each person who has used the product.\u201d<\/p>\n\n\n\n

The government disagrees.<\/p>\n\n\n\n

The DOJ\u2019s legal argument for why 100,000 names and addresses is a proportional response to a civil suit about truck exhaust goes like this. If you downloaded EZ Lynk and clicked \u201cI agree\u201d on the terms of service, you \u201cno longer [have] a cognizable privacy interest as to that information.\u201d You clicked the button. You are now, in the government\u2019s view, a person who volunteered to be identified and cataloged.<\/p>\n\n\n\n

Nobody reads the terms of service. The DOJ knows this. EZ Lynk\u2019s privacy policy was written to cover the company\u2019s obligation to respond to legal process, which is boilerplate language that exists in virtually every app on your phone. The DOJ is treating that standard legal compliance sentence, the one about sharing data \u201cto comply with a court order, law, or legal process, including to respond to any government or regulatory request,\u201d as a blanket waiver of privacy rights for every user.<\/p>\n\n\n\n

Think about what that means for about six seconds. If clicking \u201cI agree\u201d on standard app terms makes you fair game for government identification, the same logic covers every app you\u2019ve ever downloaded: Your health app. Your period tracker. Your political news app. Your dating profile. All of it.<\/p>\n\n\n\n

The broad data collection raises a question: Why does the government want this data?<\/p>\n\n\n\n

The DOJ did not really answer that question. The DOJ has not answered that question at any point during the proceedings.<\/p>\n\n\n\n

The Backdoor That Wasn\u2019t a Backdoor<\/h2>\n\n\n\n

Buried in the court filing is a detail that deserves more attention than it has gotten. EZ Lynk\u2019s lawyers claim that at a meeting on June 18, 2019, government officials asked EZ Lynk to create what the company understood to be \u201ca backdoor to the EZ Lynk System that would allow government monitoring of unsuspecting users.\u201d<\/p>\n\n\n\n

EZ Lynk said no.<\/p>\n\n\n\n

The government denied asking for an \u201cinappropriate backdoor.\u201d It did not elaborate on what, specifically, it did ask for.<\/p>\n\n\n\n

The phrasing is interesting. They didn\u2019t deny asking for a backdoor. They denied asking for an *inappropriate* one. Whatever distinction the DOJ is drawing there, it kept to itself.<\/p>\n\n\n\n

Since that 2019 meeting, according to EZ Lynk\u2019s lawyers, the government has \u201cfixated on identifying EZ Lynk\u2019s users\u201d and \u201chas been unwilling to accept our proposals that user PII be redacted or anonymized.\u201d<\/p>\n\n\n\n

EZ Lynk offered to hand over user data with names stripped out. Anonymized. The government said no.<\/p>\n\n\n\n

The government wants names and home addresses, attached to purchase histories, for every user. And Apple, Google, Amazon, and Walmart are only four of twelve third parties that received subpoenas. The others include EZ Lynk\u2019s distributors (Kinect\u2019d, Premier Performance, PPEI), developers (Mercury, Salvo), and tech support contractors (Keltek, TechIt).<\/p>\n\n\n\n

Twelve subpoenas to twelve companies. The government is assembling EZ Lynk\u2019s complete customer database from every available angle, after being told no by the company itself and after refusing the anonymized version.<\/p>\n\n\n\n

The underlying lawsuit, United States v. EZ Lynk<\/a>, was filed in March 2021 by then-US Attorney Audrey Strauss in the Southern District of New York. The complaint accused EZ Lynk and co-founders Bradley Gintz and Thomas Wood of selling defeat devices that enabled \u201cmany thousands of drivers across the United States\u201d to delete emissions controls from Ford, GM, and Ram trucks.<\/p>\n\n\n\n

\u201cEmissions controls on cars and trucks protect the public from harmful effects of air pollution,\u201d Strauss said. \u201cEZ Lynk has put the public\u2019s health at risk by manufacturing and selling devices intended to disable those emissions controls.\u201d<\/p>\n\n\n\n

EZ Lynk denied that the product\u2019s primary purpose is circumventing emissions laws and moved to dismiss. Judge Mary Kay Vyskocil partially granted the motion in March 2024, tossing one of two government claims. The government appealed. The Second Circuit revived the case in August 2025, ruling EZ Lynk had allegedly contributed to the creation of \u201cdelete tunes.\u201d The case went back to district court, discovery resumed, and the subpoenas landed.<\/p>\n\n\n\n

The legal question in the case is whether the EZ Lynk system\u2019s \u201cprincipal effect\u201d is to defeat emissions controls. That is a question about the product, about what it does, and what most people use it for. Answering that question does not require identifying 100,000 individual users by name. Nobody has explained why the government thinks it does, and the government has declined every opportunity to explain.<\/p>\n\n\n\n

The government already has evidence. The original complaint cites hundreds of Facebook posts and forum entries where purported EZ Lynk users discuss removing emissions controls. The government could pursue targeted discovery for those specific posters. It chose the dragnet instead.<\/p>\n\n\n\n

The Precedent You Should Be Worried About<\/h2>\n\n\n\n

The DOJ tried a smaller version of this in September 2019, when it ordered Apple and Google to hand over names, phone numbers, and identifying data on more than 10,000 users of a gun scope app called Obsidian 4, made by night vision manufacturer American Technologies Network.<\/p>\n\n\n\n

It was considered unprecedented.<\/p>\n\n\n\n

The EZ Lynk request is ten times larger. And that earlier case involved weapons leaving the country. This one involves truck exhaust.<\/p>\n\n\n\n

The legal framework the government is leaning on is the third-party doctrine, from the 1979 Supreme Court case Smith v. Maryland. The ruling said a robbery suspect had no privacy interest in phone numbers he dialed because he voluntarily gave them to the phone company.<\/p>\n\n\n\n

That doctrine has been crumbling. In Carpenter v. United States in 2018, the Supreme Court ruled that cell phone location data is protected under the Fourth Amendment even when third parties hold it. Chief Justice Roberts wrote that the third-party doctrine was \u201cill-suited to the digital age.\u201d<\/p>\n\n\n\n

The DOJ\u2019s argument in the EZ Lynk case is the exact kind of extension *Carpenter* warned about. The government is treating the standard boilerplate compliance language in a privacy policy, language that appears in virtually every app ever published, as consent to mass government identification. If a federal judge agrees, the same argument works for any app on any phone.<\/p>\n\n\n\n

EZ Lynk\u2019s lawyers cited Twin Bridges Waste & Recycling v. County Waste & Recycling Service, where a court denied production of an entire customer list on privacy grounds.<\/p>\n\n\n\n

The government countered that EZ Lynk lacks standing to object because the data belongs to third parties, not to EZ Lynk. The government also noted that EZ Lynk has been requesting user information about specific online posters. That is a fair point about symmetry. But asking for information about identified individuals who made public forum posts and demanding the complete customer database of an entire company from four corporations are two different things. One is discovery and the other is a census.<\/p>\n\n\n\n

The Question Nobody Answered<\/h2>\n\n\n\n

Apple and Google are reportedly planning to fight the subpoenas. Fact discovery closes September 1, 2026. Trial is estimated at two to three weeks before Judge Vyskocil.<\/p>\n\n\n\n

Justin Montalbano, president of the Car Hacking Village at Def Con, suggested the obvious alternative. Mandatory annual vehicle inspections for defeat devices would catch actual violators without building a database of everyone who downloaded an app. The government did not explain why it preferred the dragnet.<\/p>\n\n\n\n

EZ Lynk\u2019s lawyers flagged one more problem. If the government contacts users, \u201cthat would send a message that using EZ Lynk will result in the DOJ knocking at your door, putting EZ Lynk at a severe competitive disadvantage before its liability has been adjudicated.\u201d The company gets punished before a judge decides whether it did anything wrong.<\/p>\n\n\n\n

The government\u2019s response was that \u201cany implication that the government is seeking improper discovery to pursue claims against EZ Lynk System users is incorrect.\u201d<\/p>\n\n\n\n

That is an answer to a question nobody asked. The question people have been asking, the one the DOJ keeps walking past, is what the government plans to do with a database of 100,000 Americans\u2019 names, addresses, and purchase histories. And why the government needed a backdoor to EZ Lynk\u2019s system in 2019, before it had won anything. And why a government that pardoned a diesel tuner, dropped criminal charges for the exact activity at the center of this case, and introduced legislation to make emissions enforcement illegal needs to identify every person who ever downloaded the app that does the thing they\u2019re trying to legalize.<\/p>\n\n\n\n

EZ Lynk\u2019s users are not defendants. They are not suspects. They are not accused of anything. They are people who downloaded a phone app, and the government wants to know who they are.<\/p>\n","protected":false},"excerpt":{"rendered":"
