I don’t think it’s necessary. Depends on the license. I think SA is quite restrictive that way, NC is highly interpretable (as in what counts as commercial use is really unclear and my understanding is it’s intended to be) – i don’t see a problem using an ND photo in a CC-BY work, though…

In any case, i think the main issue here wasn’t w the license per se, but the misuse of it, and the issue w CC-BY or any CC license is that the original author isn’t necessarily notified so they could fix it
