Well you see, requiring companies to let farmers fix their own tractors is Socialism. And the USSR had "socialist" in the name, so Socialism bad. In the big, beautiful Land of the Free(tm) they don't do Socialism because that's commie shit.

The American Way is to let corporations fuck you over in any way that increases profits. Sure, they have the least efficient healthcare system in the world, ineffectual public education, massive wealth disparity, crumbling national infrastructure, and a different school shooting every week.

But at least they're not socialists.

A lot of vehicle manufacturers don't even give you access to their repair/diagnostic software even if you want to pay.

Tesla for example lets you pay to access their diagnostic software, so why is John Deere the bad guy here?
