'Open Design Hardware' is nice!
I like the clarity of Copyleft Hardware. The term is not meant to be tied to
opening existing designs, if that's what you get from our texts maybe we should
reword a bit.
Qi starts with existing designs, and let's their partners know we are going to
open it up, get it all into a copyleft state. Then make changes only as many
and as fast as we can manage without undermining HW quality.
But that's an internal operational restriction at Qi, has nothing to do with
the clarity of the term Copyleft Hardware, meaning that all files that make
up the hardware design are under copyleft licenses.
