The sources are available to you so that you can remove the Intel microcode yourself. Right?

Whether that gives you

a) a computer that won’t boot at all, or
b) a computer that has a security regression (missing out on important security fixes), or
c) a computer that is completely satisfactory

I don’t know.

If i remove the microcode from coreboot then the system crash after seconds of boooting, because ME partitions need a ridiculous microcode sign to keep machine ON. So we need to wash more blobs from ME to prevent microcode sign. IMHO Purism need stop using intel.
