Ok, it gets a little less worse .. well actually it seems they are just misrepresenting what kind of rights they have, because apparently they only claim copyright to the "Camelot notation and the Camelot wheel". There is obviously a copyright on the camelot wheel, but I can hardly see a copyright on the notation. Obviously simply drawing your own "Camelot wheel" is totally legit too, so this is no longer a stumbling block.
