If these companies were affected then the foundation of computing could be at risk. If you could manipulate at the hardware layer via the firmware, BIOS, ect then a threat actor could weaponize well below the operating system which brings in to question the integrity of the entire computing stack and everything above it.  The firmware and bios are like the rebar and concrete for a building. If that foundation is weak then the entire structure and anything dependent on it is at risk.
