It sounds like this is a (very common) mix up of copyright and plagiarism. Whenever I've talked about Creative Commons with artists, their most frequent concern is about others passing off work as their own. It's a widespread conflation, but thankfully it's easy to sort out; for example, The Canterbury Tales was written before copyright existed, but that doesn't mean I can claim it as my own work; that would be fraud (specifically: plagiarism).
