Isn't there already a middle solution? You can do whatever you want, but you void the warranty.

The problem with "you void the warranty" is that one person voids the warranty, then sells the equipment to someone else, and that second person gets upset with John Deere when it doesn't work. On the hardware side, we have "warranty void if seal broken"; but there's no easy way for someone buying used farm equipment to know if someone messed with the software.

  Yes it is? See Chromebook for example.

    What's so magical about CBs? With physical access, you can reflash the boot firmware and put unsigned OS images on them without any ugly devmode warning screens. The only alternative is complete lockout and walled garden, thankfully Google didn't go that route in this case.

      Have things improved with CBs lately? I still have Acer C710 CB collecting dust. Reflashing the boot firmware was not really an option back when I checked.

        IDK, I have an ARM CB and here removing the devmode warning should in principle be just a matter of downloading CrOS's modified uboot, commenting few lines, building it and writing to a SPI flash on the board. At some point I even wanted to do it for fun but the flash chip seems to be hidden somewhere under heatsink and the perspective of messing with this white silicone goo for no practical gain was enough to stop me.

No, that's an imaginary problem invented to rationalize this bullshit. I don't think there actually exist people so ignorant to not realize that buying used hardware comes with caveats and that you usually get what you paid for.

    Based on what I read and hear about us laws and how they are enforced this might very well be a real problem there. A company I worked for decided to settle after someone broke in, stuck something in the safety switch and got injured while illegaly operating a machine we had made. The reasons were simple: 1. There were no sticker saying this was bad. (But as mentioned we had other safety measures that were deliberately overridden.) 2. While we had a fair chance of winning the costs and risks were simply not worth it. Lessons learned: if something goes to the US, make sure the stickers are in place.

And this shows that if Deere cared about liability and not about ripping customers off every time they need to repair something, they would use stickers instead of DRM. And you can laugh at safety stickers, but IMO they are a good thing. They mean that your responsibility is limited to providing basic safety interlocks sufficient for the intended use and informing what is and what isn't intended use. Everything else is user's problem, as it should be. I certainly prefer this over wasting manufacturers' time on elaborate idiot-proofing and then later wasting hackers' time on breaking it.

  Why not just hash the contents of flash and see if it matches a dealer specified value? If JD had a reasonable port to the flash, it would be easy to read it out and see if your phone (or whatever) thought it had the correct image.

  Used equipment has always been a crap shoot that comes with few guarantees and will continue to be so for every industry in existence. The fact that used equipment repair could in theory effect the perception of the john deere brand and tangentially their future sales doesn't imply that they have a legal or moral right to prevent it.

  This is why our legal system comes to the sane conclusion that a person who gets "upset with John Deere" for that reason has no legal standing because they bought it used. That's the incentive to buy the warranty.

No, it looks like John Deere can sue your ass for doing any modifications to your own tractor,since it bypasses their copyright protections and therefore in their opinion, brakes some laws. If it was as simple as losing warranty no one would care.
