Copyright law is far to generous to the "artist". If you invent a cure for cancer you get exclusive rights for your invention for 20 years. If on the other hand someone writes a song about your invention they get exclusive rights to the song for their lifetime plus 50 years. The length of a copyright should be severely curtailed, but unfortunately this will never happen.

Copyright lasts to long
