Most likely. The open source movement in software was still relatively recently and quite radical. The hardware companies are still stuck way in the past.
If only. In the past it was common to provide schematics of your hardware in order that people could repair it. This was common for consumer products, industrial, instrumentation, test gear, almost everything. For example, the manual for the Amiga 500 had the schematics in it.
While I was at University I made some money by repairing DJ-hardware. Controllers, CD-Players and Turntables. There things are often expensive, but they are quite easy to repair because there are detailed service manuals available. Not on the official sites, though.
You wish they were stuck in the past. People like Steve Wozniak often designed new stuff only based on the manuals that back then had complete schematics in them. They didn’t have enough money first to buy anything but that information later on resulted in sales.
Example: in the past my friend bought Moog Prodigy synthesizer and along with everything it also came with all the electronic circuitry diagrams. Good luck finding anything like this with the modern hardware.
