Mallory, a malfeasor, spots Bob's newsletter in a cafe. She smells opportunity. She creates a derivative of Bob's piece, comprising "Quul Bal Bal Fol." Mallory publishes this under her own name, claiming authorship (as she is entitled to do, under CC-0).
That is, under Bob's CC-0 license. Also, Mallory *does not* mention or credit Alice or Bob in any way. And finally, to be clear, Mallory *does not* publish "Quul Bal Bal Fol" under a Free Culture license.
