Amidst all the hype for firmware security, one point missing in these discussions is how many points of failure these guys have added. 1) Intel/AMD for ME/PSP 2) Dell for bios signing keys 3) MS for secureboot keys 4) American Megatrends, Phoenix, etc., companies that people don't even know exist, who actually write the bios code. If the threat model is nation state attacks, there is plenty of surface area here in the circus.
