[Cheetah26]

I think the ideal solution here would be if companies were required to ship an open source driver, and then optionally offer a proprietary driver for an extra fee which includes whatever 'special sauce' (as another comment put it) that they don't want to release.

The example I'm thinking of is Nvidia's newer GPUs and DLSS. The hardware would come with open drivers, but if you want the upscaling that's an additional fee. While maintaining additional drivers is more work for companies, I think they'd actually benefit from this because it could be a recurring revenue stream for older hardware.
