R2R goes beyond farmers repairing their equipment.
There is massive amounts of IP in the controllers of modern equipment that not only competitors but nation states would love to be able to get their hands on.
Some nations would love to know how this is accomplished so they could copy and reproduce in their "independently owned"(state) factories and sell worldwide.
I've seen them do it on multiple products - they buy the product/service assemblies, break it down, reverse engineer the physical components then spend years trying to figure out how to make it work right. Imagine if they could break into the controllers and eliminate that multi-year delay?
Forcing them to allow access to this info would destroy competitive edge built over decades.
Ex:
Or how about compare these 2 machines, it won't take much imagination to discern which was developed first and which was a nearly identical copy other than paint color.
Sure, I have a vested interest in Deere maintaining their competitive/technological edge but it really boils down to valuing innovation and preventing it from being diluted by entities that don't care about domestic patent/copyright protections.
