"hardware whose interiors and circuits are known and well described"
Best not to get confused here. "Open Hardware" doesn't actually mean that.
Maybe that's what you think of with the term, but as has been pointed out in
this thread, the actual definition of their so-called "Open Source Hardware
Certification" is still up for definition. So it'll be necessary to see and
wait if that make it in or not.
"which 'just' respects your freedom"
It seems you're trying to present the so-called "Open Source Hardware
Certification" as something more fundamental that the RYF program. I
disagree. If you've kept up on discussions, the FSF has indicated their
willingness to go in that direction themselves, pending discussions of how to
do it well (there are definitional problems going in both directions.) So the
so-called "Open Source Hardware Certification" would remain a duplicate in
any event.
