It's pretty clear to me what a reasonable solution to this would be. If you buy a laptop you don't "own" the OS you have a license to it and you can install another OS on it you just won't be able to get tech support for the non-standard OS. If you buy a tractor you should be able to do the same and the manufacturer should be required to provide enough information about the hardware systems and their functions that if someone wants to write a open source tractor OS they could.
