Captive aftermarkets are roughly the biggest hidden cross-subsidy in consumer goods imo.. printer and tractor OEMs price the unit near cost and pull the lifetime margin out of parts, service, and locked firmware. That's why right-to-repair is one of the few issues where farm states and urban progressives end up in the same column.

Right To Repair is a fundamental of freedom from oligarchy.

It is literally the question of who owns the things we buy. Or, are we forever just de-facto renting those things, while sending all the data to the corporate overlords?

It seems obscure, but is a key element of freedom and democracy.
