They Hacked McDonald’s Ice Cream Machines—and Started a Cold War

Press the cone icon on the screen of the Taylor C602 digital ice cream machine, he explains, then tap the buttons that show a snowflake and a milkshake to set the digits on the screen to 5, then 2, then 3, then 1. After that precise series of no fewer than 16 button presses, a menu magically unlocks.
The secret menu reveals a business model that goes beyond a right-to-repair issue, O’Sullivan argues. It represents, as he describes it, nothing short of a milkshake shakedown: Sell franchisees a complicated and fragile machine. Prevent them from figuring out why it constantly breaks. Take a cut of the distributors’ profit from the repairs.
That's a more and more common business plan, sadly.
