Then how is the “Vikings D8 Workstation” RYF certified? It ships with a Crucial hard drive or Crucial SSD, the firmware for which are not open source, and can be updated via a special dd module from Grub. Such an update has been necessary in the past to fix Crucial drives soft locking due to a smart counter error after 5000 hours of on time. Obviously, I don’t expect you to have personal knowledge of the certification process for another vendor’s item, but if your analysis is correct, it should not be RYF certified.
