Indeed. But I would set the blame at manufacturers at this view. The last time I got a circuit schematic was with my Icom radio. And even with that, still received none of the firmware. "Proprietary". Ideally, mechanical drawings, circuit schematics, and firmware would enable a great deal of repair and 3d party parts replacement. But the idea of allowing that isn't capitalist - in fact it goes directly against selling more to replace (planned obsolescence). I would heartily like to have a library of parts I can refer to, designs I can 3d print parts as needed, firmware access to correct issues. But this all flies in direct opposition with "commercial" opportunities, save a very few. It's also why I highly prefer free/open source hardware, with as much details how it works available. That's the only way to guarantee that your hardware doesn't get abandoned - there's always someone who has a similar problem.
