> I just feel like "self hosting" isn't a real company solution to a kill switch, so I'm not sure how you have a kill switch without interacting with the company in any way, even if you're not John Deere. You can’t have any (online) interaction with the company. Even OTA updates can’t be trusted if the company wants to act against your interests or the interests of your country. Individual farmers need 100% control and I would argue that the only way to accomplish that is to require physical access for all updates and no kill switch at all. Tractors aren’t close to cell phones. No one is naively and unknowingly buying a stolen tractor off of Craigslist. Engraving serial numbers on parts is a viable theft deterrent if everyone in the industry refuses to buy stolen parts.
