The right to repair thing is a spectrum. On the one hand you have the John Deere inkjet model. But on the other end you have the normal car manufacturers who don't make it impossible, but who incentivize using 1st party repair. Are we talking about that being against right to repair? Because that feels somewhat hard to legislate.

E.g: A car has 1 year warranty. But the warranty is extended by one year so long as you service it with manufacturer, not a third party. This doesn't prevent me from servicing with a third party for half the price, but it might not be worth doing that. And I would think twice about buying a car which is only a few years old unless it's serviced completely at first party, due to issues that could arise with warranty claims.

Could legislation be made that says "If you repair at a third party, or even repair yourself, and you know what you are doing/do it according to the recommendation, then the manufacturer has to give the same warranty they would have if you serviced it at them"? Because that feels insane. The warranty is just a kickback for using their expensive service, getting you to the service place/showroom regularly etc.
