Would they have to recall their boxes if wikipedia
decided to destroy
the contribution history and they couldn't find any way to reference
it? Can their competitors now use the same designs for their boxes if
they reference wikipedia? Seems a little farcical to talk about all
this stuff as none of GNU's licenses have been tested in court yet
right?
I specifically said that it wasn't anywhere near enough for actual
compliance, and it was never intended to be. It was intended to be a
suggestion for how to show good faith and do what normal people (ie.
not lawyers) would consider fair. Satisfying the lawyers is far
harder, and, as you say, until it's tested in court we're not even
sure how to do that.
