Once upon a time there used to be a wiring diagram taped to the inside of your TV cabinet or refrigerator to aid in the diagnosis and repair. Nowadays the chips on the motherboards of these products have the identifying marks sanded or lasered off and fuses are burnt to prevent repair and force consumers to toss the product when it fails. Manufacturers benefit and consumers suffer.
This is the heart of the matter. I think R2R should be focused on the idea that the OEM can and should have some "product lifecycle" where they can hold proprietary design data captive while the products are under a reasonable warranty period with them being the provider of repair parts and data. However, when they decide to move on from those products and make them "end of life" they should be required to provide design schematics of suitable nature for appropriate repair and/or remanufacturing.
A good example - you sold me a reverse engineered hydraulic block that you produced for my B7100 which is arguably much better than the Kubota OEM part. It was a fairly simple part, but definitely not something easily obtained through the Orange mothership. There's a lot of stuff like that for the older tractors. I know why OEMs do not want to do that,
because to them each fixed tractor is one less potential new sale.
An alternative idea that I've had is that after a certain period of time, the OEM must either public domain or provide upon request the design schematics so that someone could machine a new part or repair something. Naturally, it would be on their dime, on their time, with no warrantability or liability for future use. "Here's the recipe, but you're on your own if you make one" kind of thing. In our litigious society, it will have to be written into law that the OE manufacturer is absolved of liability for anyone making repairs or replacement parts from their public domain information.
