I think something like the automotive market would be a huge step, you can buy a part from Ford or GM and even if it’s something that need programming you can pay a small fee ($40 per VIN valid for 2 years for GM) and program it yourself with any J2534 compliant VCI, you can also pay to access technical info like wiring diagrams and TSBs however if you want to repair an electronic device you have to resort to fake/ stolen/ refurbished parts pirated schematics and shady software tools.
