Copyleft restricts individuals as well. What about plagiarism? Is it theft? Copyright is about the holder of the IP being able to control the use of the IP. Consumers can either accept those terms or not. I don't know what the penalties should be for copyright or copyleft violations but there should be some. I am also not sure about the best way to enforce it. SOPA or OPEN isn't the answer but there is a problem.
