As a lawyer that sues car companies, and the spouse of a lawyer that does work for car companies, I can assure you that lawyers aren’t the ones who convinced them to make things more proprietary and difficult to repair.
I do not think lawyers literally encouraged it, I just think that they are expensive and going proprietary helps avoid issues.
What's your take, though? Genuinely interested. It is widespread across the entire industry, so there appears to be an industry-related driving factor for it
This is interesting to me. Do conflicts of interest with both of your respective employers come up?
