Dumb argument. There are tons of after market car parts available for purchase.
And I bet tons of legal precedents skewering drivers who proceeded to render their car unroadworthy by screwing with it. In case of accident, someone who effed it deserves the book thrown at them.
Till then, you buy, you own.
Gotta try harder, you ain't going to be taking on the equivalent of Pai's responsibilities lobbying for "regulating" your chosen industry with such a feeble effort.
BTW, wouldn't sharing source code, if it's not aimed at circumventing a law, be covered by the First Amendment?
