I'd believe that, which is why NC combined with SA seems pointless
to me. If NC derivs dwindle to zero, that those few derivatives are
sharable is moot.

So then my question is "If NC-SA doesn't make sense, why is it the
biggest slice of the pie chart?"

Or to flip it around, "Is there something that CC could do to better
explain the licenses such that combinations like this become less
common?"
