Hardware hack hit Supermicro motherboards?

This article finally explains why a large number of perfectly good Supermicro motherboards suddenly showed up on surplus markets two years ago.
A great deal has been left out for various reasons, but I can deduce a little more. The tiny size of these chips and the small number of leads means they were not handling the main computing tasks. They were on a much lower bandwidth control circuit.
These chips could affect the system management engines that bring the really baroque designs of modern processors up at boot, and may shut them down if there are faults or patches to apply to OS or firmware.
I'm not surprised big companies simply junked the entire board and switched to other designs. Tracking this down in a typical server farm would be a nightmare.
