The Machine That Launched a Federal Investigation
Walk into any McDonald's in America and ask for a McFlurry. There's a 12% chance you'll hear the same response: "Sorry, the ice cream machine is broken." On any given day, one in eight McDonald's soft serve machines sits idle, displaying cryptic error codes that nobody except Taylor Company technicians can decipher. This isn't a quality control problem. It's a $900 million lawsuit, an FTC investigation, and a case study in how repair monopolies extract profit from franchise owners while frustrating millions of customers.
The story begins with a single company's 70-year grip on McDonald's frozen dessert infrastructure and ends with two federal agencies asking the Copyright Office to legalize what should have always been legal: fixing your own equipment.
The Taylor Monopoly
Taylor Company, based in Rockton, Illinois, manufactures virtually every soft serve machine in McDonald's 13,000 U.S. locations. The relationship dates back to the 1950s, when Ray Kroc standardized the chain's equipment specifications. Over seven decades, that standardization calcified into a de facto monopoly. McDonald's franchise owners don't choose their ice cream machines. Taylor is the only approved supplier.
The machines themselves cost $18,000 to $25,000 depending on the model. They're mechanically sound, built to last 20+ years. The problem isn't the hardware. It's the software.
Taylor machines run proprietary diagnostic systems that display error codes when something goes wrong. Simple problems like "hopper too full" or "cleaning cycle incomplete" trigger cryptic alphanumeric codes. The machine locks itself down. It won't dispense product until the error is cleared. And franchise owners can't clear the errors themselves because the diagnostic interface is password-protected and hidden behind what the company calls "technological protection measures."
Only Taylor-authorized technicians have access to the diagnostic system. Only they can read the codes, identify the problem, and restart the machine. The average wait time for a service call: 90 days. The average cost of lost soft serve sales during a breakdown: $625 per day. Over three months, that's $56,000 in revenue disappearing while franchise owners wait for a repair person to drive out and press a reset button.
This arrangement generates substantial revenue for Taylor's service division. Franchise owners pay per-incident service fees, plus annual maintenance contracts. The repair business is wildly profitable precisely because alternatives are illegal.
Enter Kytch
In 2019, two California entrepreneurs named Jeremy O'Sullivan and Melissa Nelson founded Kytch, a startup that built a $1,000 device designed to solve the diagnostic lock-out problem. The Kytch Solution was a small computer that connected to Taylor machines via the internal data port. It intercepted error codes, translated them into plain English, and displayed them on a smartphone app. It didn't modify the machine. It just read the data that was already there.
For franchise owners, the device was transformative. Instead of waiting three months for a Taylor technician, they could diagnose problems in real time and fix simple issues themselves. A sensor reading gone wrong? Restart the cycle. Ice cream mix running low? Refill the hopper. The device didn't void warranties or bypass safety systems. It just gave owners visibility into their own equipment.
Kytch tested the product at multiple McDonald's locations throughout 2019. Franchise owners reported significant reductions in downtime. The startup raised $2.5 million in venture funding. By early 2020, hundreds of McDonald's operators had installed Kytch devices in their stores. The company was on track to reach 1,000 installations by year-end.
Then McDonald's corporate sent an email.
The November 2020 Email
On November 2, 2020, McDonald's USA sent a message to all franchise owners recommending they immediately remove Kytch devices from their soft serve machines. The email claimed the device "posed a safety risk," could "void equipment warranties," and "may be obtaining intellectual property from McDonald's and the equipment manufacturer."
Sales of Kytch devices stopped overnight. Franchise owners who'd already installed the product pulled it from their machines to remain compliant with corporate guidance. Kytch's revenue collapsed. The startup had spent two years building a solution to a real problem, secured paying customers, and was shut down by a single corporate memo.
The email wasn't spontaneous. According to court documents filed in March 2022, McDonald's and Taylor had been coordinating behind the scenes for months. Taylor had allegedly gained access to Kytch devices through trial participants, studied the technology in password-protected areas of the interface, and shared data with McDonald's corporate to develop their own competing product: a system called "Taylor Open Kitchen."
The smoking gun came three years later during discovery in Kytch's $900 million lawsuit against McDonald's and Taylor. Internal emails showed Taylor employees discussing how to "undermine" Kytch's business, how to position the device as a "safety threat," and how to work with McDonald's to ensure franchise owners received messaging that would kill demand for the third-party diagnostic tool.
None of the safety claims held up. No Kytch device ever caused an injury. No warranty was voided. The intellectual property theft allegations were never substantiated. The email wasn't about protecting franchise owners. It was about protecting Taylor's repair monopoly.
The Right to Repair Battle
Kytch's lawsuit is ongoing as of March 2026. A California judge rejected McDonald's motion to dismiss the case in September 2022, allowing claims of defamation, trade secret theft, and anti-competitive behavior to proceed. Taylor Company declined to retract its statements about Kytch. Jeremy O'Sullivan told reporters: "Taylor tried to falsely smear Kytch as dangerous and ultimately destroy our business that we've been building for the past 10 years because our technology gave machine owners the right to repair their own Taylor machines rather than having to spend huge dollars fueling Taylor's wildly successful repair racket."
The legal battle exposed a broader problem: manufacturers across industries using copyright law to block independent repair. The mechanism is Section 1201 of the Digital Millennium Copyright Act (DMCA), a 1998 law originally written to prevent CD and DVD piracy. Section 1201 makes it illegal to circumvent "technological protection measures" on any electronic device.
Repair advocates argue that diagnostic locks aren't piracy protection. They're anti-competitive barriers that force equipment owners to pay manufacturers for repairs they could perform themselves. But under current law, bypassing a password-protected diagnostic system to fix your own property is a federal copyright violation.
Every three years, the U.S. Copyright Office reviews requests for exemptions to Section 1201. Organizations like iFixit and Public Knowledge have successfully secured exemptions for jailbreaking cellphones, repairing video game consoles, and servicing certain medical devices. In 2023, they filed a new petition asking for an exemption covering "commercial and industrial equipment," with McDonald's ice cream machines as the lead example.
In March 2024, two federal agencies weighed in: the Federal Trade Commission and the Department of Justice.
The Federal Government Chooses Sides
The FTC and DOJ filed an 18-page joint comment with the Copyright Office supporting the exemption request. The document is a remarkable piece of regulatory writing because it doesn't mince words.
From the filing: "Ultimately, by limiting access to data and software functionality necessary for independent repair and maintenance, TPMs can be used to squash competition for replacement parts, repair, and maintenance, thus ultimately limiting consumer choice."
The agencies argued that repair monopolies harm consumers, limit competition, inflate costs, and create artificial dependencies. They cited research showing that unplanned manufacturing downtime costs businesses an average of $260,000 per hour. When equipment owners can't legally fix their own machines or hire independent technicians, they're forced to wait for manufacturer-authorized service regardless of cost or delay.
The comment specifically addressed McDonald's ice cream machines. The FTC and DOJ noted that franchise owners face 90-day average wait times for Taylor service calls, during which machines remain offline. They noted that breakdowns cost operators $625 per day in lost sales. They noted that third-party solutions like Kytch existed but were effectively shut down by legal threats and manufacturer coordination with the franchisor.
The agencies asked the Copyright Office to grant the commercial equipment exemption and to make clear that diagnosing, servicing, and repairing devices you own is not copyright infringement.
In August 2023, iFixit performed a teardown of the exact Taylor C602 model used in McDonald's stores. Their technicians found the machine mechanically straightforward to service. The barriers weren't engineering complexity. They were legal. Kyle Wiens, iFixit's CEO, said: "Copyright law isn't supposed to get in the way of ice cream, and today the FTC and DOJ voted in favor of frozen goodness for all."
The Copyright Office held public hearings in April 2024. As of March 2026, the final ruling on the commercial equipment exemption has not been issued. If granted, the exemption would legalize what Kytch was doing: reading diagnostic codes from machines you own to perform your own repairs.
The Bigger Picture
The ice cream machine saga is a microcosm of a much larger fight over who controls repair. John Deere uses similar diagnostic locks on tractors, forcing farmers to drive equipment to authorized dealers for software fixes they could handle themselves. Medical device manufacturers lock hospitals out of servicing ventilators and imaging equipment. Auto manufacturers increasingly use software pairing to prevent third-party parts replacement.
In each case, the business model is the same: sell the product, then monetize the service tail by making independent repair illegal or impossibly difficult. Manufacturers argue these restrictions protect safety, preserve warranties, and prevent intellectual property theft. Repair advocates point out that these same arguments were used to oppose auto repair shops in the 1970s, electronics repair in the 1990s, and smartphone repair in the 2010s. None of the dire predictions materialized.
The FTC conducted a three-year investigation into manufacturer claims about repair restrictions. Their 2021 report to Congress concluded: "There is scant evidence to support manufacturers' justifications for repair restrictions." The agency adopted a bipartisan enforcement policy supporting the right to repair and has since taken action against Harley-Davidson, Weber grills, and Westinghouse for illegally conditioning warranties on manufacturer-authorized service.
McDonald's and Taylor are now in the crosshairs. The Kytch lawsuit is seeking $900 million in damages for defamation, trade secret theft, and tortious interference. The discovery process has produced internal communications that will likely be cited in antitrust enforcement for years. And the Copyright Office is considering whether the legal framework that enables this kind of monopoly should continue to exist.
What Franchise Owners Actually Want
The people caught in the middle are McDonald's franchise owners, who pay $18,000 for machines they can't legally service, lose $625 per day when those machines break, and wait months for repairs that should take minutes.
Several franchise operators spoke to industry press on condition of anonymity (McDonald's franchise agreements include non-disparagement clauses). Their complaints are consistent: Taylor machines aren't bad equipment, but the service model is predatory. When a machine throws an error code on a Friday night during a summer rush, franchise owners can't call an independent technician. They can't pay a premium for emergency service. They can't even diagnose the problem themselves. They can only wait for Taylor's service schedule to accommodate them.
One operator in the Midwest described a three-month stretch in 2023 where their machine was offline more than 40% of the time. The problems weren't mechanical failures. They were sensor glitches, calibration drift, and cleaning cycle interruptions. All issues that could be resolved in minutes with access to diagnostic data. Instead, each incident triggered a service call, a multi-week wait, and thousands of dollars in lost sales.
When asked why McDonald's corporate doesn't pressure Taylor to improve service or open up diagnostics, operators point to the long-standing relationship between the companies and the lack of alternative suppliers. Switching to a different manufacturer would require re-engineering franchise equipment specifications across 13,000 U.S. locations. It's technically possible, but organizationally complex enough that the path of least resistance is accepting the status quo.
The Kytch device offered a middle path: keep Taylor machines, but remove the service monopoly. That's precisely why Taylor worked to eliminate it.
Where Things Stand in 2026
As of March 2026, three parallel processes are underway. The Kytch lawsuit against McDonald's and Taylor continues in California federal court, with trial likely in late 2026 or early 2027. The Copyright Office has not yet issued its ruling on the commercial equipment repair exemption, though industry observers expect a decision by mid-2026. And the FTC's broader investigation into repair restrictions continues under its 2021 enforcement policy.
Meanwhile, 12% of McDonald's ice cream machines remain broken on any given day. Franchise owners continue to lose $625 per day per broken machine. Taylor continues to bill for service calls. And customers continue to hear "sorry, the machine is broken" when they order a McFlurry.
The situation has become a cultural meme, but the underlying problem is dead serious. When manufacturers can use copyright law to block repair of equipment that customers have purchased, market dynamics break. Competition disappears. Prices rise. Service quality degrades. Innovation stalls.
The fight over McDonald's ice cream machines isn't about soft serve. It's about whether we're buying products or merely licensing them. It's about whether ownership means control. And it's about whether federal policy should protect monopolies or markets.
Two federal agencies have taken a clear position. The courts are beginning to agree. Now it's up to the Copyright Office to decide whether reading an error code on equipment you own is piracy or common sense.
