If you assume they only get a buck or so on a "label release" and average out the freeloaders and the payers, I might guess Radiohead made out a bit better with their experiment . . . this all of course assumes the method of figuring out who paid and how much is accurate.
FWIW.

edit: I paid about $10 and I am now hooked on the album! It takes a few listens to absorb.
