I suspect that John Deere and friends will find a way to challenge this in court and -- if they eventually lose -- find a way to maliciously comply with the law. Their behavior has been actively hostile to their customers for years, and they have zero incentive to change. Like Apple's repair kits mentioned in another comment, I suspect their strategy will involve providing tools that cost nearly as much to rent as it…
Name, shame, and industry blacklist Deere product managers. It's the only way. Stop acting like there's nothing that can be done.
Naming and shaming individuals (besides a CEO) within a company is unnecessary, and can cause destruction to lives, families, and communities that have nothing to do with the problem. It also overestimates the individual agency these people hold over what is most often a cultural and policy issue at a company.
