Every single manufacturer has been pulling this stunt on owners of their equipment, for 30 years or more - but it's got so much worse in the last 8-10 years, as electronics on machinery and automotive multiplied like flies around a cow pat.
The auto manufacturers were the first to go down kicking and squealing, they got dragged through the courts to make them release technical repair info. This started when auto owners had a fender-bender, and the body shop needed to access the electronics in the vehicle to be able to repair it.
The auto manufacturers were insisting that the electronics could only be serviced in the dealership - citing the big bogeyman - "safety problems", if "unauthorised" people were allowed to access the vehicles electronics.
It meant the insurance companies were having to pay to haul the vehicle back and forth between the body shop and the dealer.
It was a BS setup, and everyone knew it. I think the insurance companies initiated the lawsuit, and they won comprehensively.
JD just saw the writing on the wall for them, because the rumblings were getting louder every day. There was talk of class actions.
You have no idea how angry so many Australian farmers were, over JD's insistence on keeping a stranglehold on their technical repair information, and demanding that JD technicians be used exclusively.
As one Australian farmer said, "I bought the tractor, I own it. I should be able to repair it myself, modify if I need to, or get other, closer and more readily available repairers, to fix it."
Here in Australia, you can be a couple of hundred, to a thousand kilometres from a JD dealer. You generally find there's a wait to get a technician on site, because they're the people most under the pump.
I tried to find a local auto electronics technician to diagnose and repair a 2010 Ford Ranger with (diesel) engine problems for me recently - and all the ones I called, had a 3 to 4 week backlog of work.
Even the local Ford dealer couldn't look at the Ranger for a week, and they were the ones who finally worked on it. They still struggled to repair it satisfactorily, and gave it back to me, with it still not starting properly. I had to finish diagnosing and repairing it myself.
When you have major income relying on this high-technology equipment to function properly and be repairable in quick-smart time, you aren't going to buy it again when it causes you losses.
I find that many heavy truck owners are now looking for older trucks to recondition to as-new, as they regard them as more reliable, and less trouble to fix.
