@Suiseiseki By "you can look at the circuitry" logic, all unencrypted software gives you freedom 1 because you can look at the binaries. Indeed, it's much easier to look at the binaries of most proprietary software than to read the ROM from a CPU's die – and for Goldmont / Goldmont Plus chips, it's easier to decrypt and disassemble the microcode updates than to get at the actual ROM microcode.
RYF's secondary embedded processor exception should apply to a GPCPU's microcode as well.
