This behavior can be found in all markets out there, regardless of the scope. And then comes beauty of free market - over longer term, taking acount bigger mass of farmers for example, more desired product should win. There are many tractor manufacturers, and if John Deere is deemed cp manufacturer in long term, some other makers will eat its market share, either by providing simpler machinery (ie trend mentioned in article when farmers buy older models), or open one. If farmers as a whole are "not-so-clever" though, and they keep buying new ones (ie voting with their money for fragile new tech), then they deserve the new tech "punishment". Lesson to be learned here - be conservative about new technology and buy only long-proven solutions, regardless how much average HN Joe might not like this non-cool approach. Also, fully agree that they shouldn't be made any more special than other jobs. Maybe ideal would to completely lose warranty (ie like iphone jailbreak), but making it criminal act is way too much.
