Oh, I thought I remembered them having dropped that because it was hard to define and actually reducing freedoms or something. Perhaps that was the FSF/OSI standpoint instead (though GPL never had it, so idk where this idea came from). I stand corrected about it being "previous" :)
There was a strong advocacy push for dropping NC or at least renaming it CRR (commercial rights reserved) to be clearer. But CC decided that dropping it for v4 would likely just lead to people continuing to use the v3. And if they use NC anyway, better to at least have the updated legal language than the outdated version.
