has NVIDIA engaged in similar illegal or unethical practices to that which ARM carried out against luc verhaegen, which we know were and are sanctioned by the CTO of ARM?
Sorry I chopped it off to keep the conclusion only. Nvidia switched to requiring signed binary firmware with a blown fuse for any maxwell or newer card to run effectively blocking the work by the libre driver and delaying the release of the signed binaries to 2 years after the cards are actually released to the market. So they are actively blocking reverse engineering.
