Which is to say, every system in actual widespread use. All such CPUs, GPUs, storage devices, displays, etc. run closed microcode and firmware. It'd be funny if it wasn't so profoundly sad.
And even if they didn't, the silicon design is again, closed. And even if it wasn't closed, it's some fab out somewhere that manufactures it into a product for you. What are you gonna do, buy an electron microscope, etch/blast it layer by layer, and inspect it all the way through? You'll have nothing by the end. The synchrotron option isn't exactly compelling either.
I'll just highlight this excerpt of your own words for you, and usher you to evaluate whether your position is even internally consistent.
