chips limiting what kind of software can be run sounds absolutely awful and would be a huge overstep in government power. once I buy a piece of hardware I should be able to run whatever I want on it.
Sure, until it gets to the point where you're no longer able to just "buy a piece of hardware". Then it'll suddenly sound like a pretty sweet deal. Like when Nvidia nerfed ETH mining back when that was still a thing. That too was done to give more people access to hardware, not to take away their freedom.
