Your probably AI generated answer thread in parts as well as many of its contained arguments are "unsubstantial" and "utter nonsense". You sound like the typical MacOS user, and you actually argument against your own product; are you Daniel Micay? 😉
"Oh, we cannot prove it anyway, so we have to believe them..." This is ridiculous.
Why wouldn't there be a way to prove that the chips are made open source if the architecture is known? Even if you had to destroy them to check it, you could still take random samples.
Why not programmable architectures/FPGA?
Why closed source drivers?
Why reverse engineering?
Why are practically all chips under US license produced in US or franchised in Taiwan and therefore under "Patriot Act"? The most probable attack vector is inside the compromised ME.
