I'd argue allowing farmers to fix their own stuff is way better (and safer) than them having to seek out sketchy foreign vendors/hacks in order to fix their own equipment on the black market as an alternative.

Obviously the majority of farmers aren't going to be going into the software and editing it themselves, but instead paying reputable companies in the industry to do the programming/fixing/debugging for them.

Companies like John Deere could embrace this by releasing a ton of guides and self-learning classes to teach these same farmers how to do basic coding, repairs, debugging and etc. themselves. Could start a whole new wave and generation of tech-literate and educated farmers which would be better for all involved.
