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.
For example, I completely trust Emacs maintainers, as I have yet to see any malice or dark patterns coming from them. The same applies to other free and open source software I use on a daily basis. These projects respect my privacy, have nothing to hide, and I have no problem trusting them.
On the other hand, I see more and more dark patterns coming from Apple, say when signed out of their cloud services. They pour millions into their privacy ads, but I do not trust them to act ethically, especially when money is on the table.
Does this not make sense?
