Are there any OEMs whose service manuals are hard to find? I restore cars and motorcycles and have never had trouble finding a pdf or hard copy for around $20. Its good that they are doing this though a lot of the secrets I’d want to know about an electric motorcycle are about the ECU when that software is some of the most tightly guarded of any.
I acquired an old Sony CMT-EX1 CD player a while back and was tinkering around with it. I found the service manual online and was blown away. There are pinouts! Block diagrams [0] for the PCBs! Capacitor inventories! I wish we still did this for consumer hardware. [0] https://servlib.com/sony/audio/cmt-ex1-hcd-ex1.html?start=29
Making old technology viable instead of buying new one, or even worse tinkering with it and unlocking or adding new functionality corporations reserved for higher end models, professional equipment or just outright didn't want to implement assured it will never happen. In the past only few tinkerers actually cared about this. Now everything is on the internet and everyone have access to it. This is a season for planed obsolescence after all.
I'm not saying it's good, it's just what it is.
