Regulations were put in place to prevent manufacturers from opening their own stores right next to the dealers they worked with. Dealers assume some risk when they take on inventory. Apparently it’s not like a bookstore where any unsold copies just go back to the publisher. It’s still a flimsy justification though and enshrined these middlemen who then enshittified everything. Worse, in some cases manufacturers are entirely prevented from selling direct, even if they don’t work with dealerships. It’s too much.
