@asu @marcan @darkling @mjg59 As far as I can guess, it breaks down into two fundamental concerns:
1) We can't allow our flock to be tempted. Make them rip out anything that would run proprietary software.
2) We need a way to "grandfather" into compliance the devices we have already been using. If we say the proprietary firmware in the Embedded Controller (and countless other cores) in RMS' Thinkpad is "just part of the hardware" for <some reason> we can pretend it doesn't exist.
