Nobody is arguing that a person is entitled to royalties as a performer of traditional music or song. However when someone has the gall to attach their own name with a copyright mark to something that they did not create it equates to at least moral theft even if the work was public domain and free for the taking. If someone by finding an unmarked grave, felt that would entitle them to pilfer it, we would have little sympathy with their claim. To steal from an unknown or long dead creater of the work is no different, in my opinion.
