Coreboot requires Intel/AMB blobs, you can disable most of the ME, but it's still binary-blobbed to hell. Also none of that is done by Intel/AMD.

OpenPower has the entire firmware Apache licensed, see the link I gave. that's WAY more than any Intel/AMD CPU. Even all the secure-boot stuff is open(Apache Licensed).

Joining the OpenPower Foundation is free for < 300 employee companies, academics and individuals. see the membership kit: https://openpowerfoundation.org/membership/how-to-join/

If you had read any of the links I gave you would have seen all of this for yourself. I provided proof. Please provide proof of your claims :)

Is it perfect, of course not. I never claimed it was, but it's WAY more open than anything else out there, except perhaps RISC-V.. except I don't believe any of the hardware for RISC-V is open at all, and none of the hardware that I'm aware of is yet able to compete with x86.. YET.
