Afaik in most of the world car companies are required to offer the tools to third party service stations at a reasonable price. Then again if you control the full supply line you can make repairs near impossible so there is that. And also reasonable does not mean economicaly viable unfortunately.

I'd love to see it made a requirement to be affordable to end users but that is a bridge too far I guess. Most mechanical tools are affordable enough but electrical is still insanely expensive up to the point you are nearly required to buy Chinese copy/bootleg variants.
