Car manufacters is an interesting case. Here in the EU Volkswagen has a different maintenance and repair policy depending on whether the car stayed in the network for revisions or not, and I think aftermarket changes would also matter. They’re not refusing or blocking anything, just putting a price tag on consumer’s freedom to do what they want.
