probably there is a more detailed account of this incident and it is the origin of the abomination of copyright law
copyright is almost exclusively used by rentseekers and does not in fact benefit creators
just look at the huge publisher monopolies that exist and have existed throughout the 20th century... HMV, RCA, Warner Bros - many many movies and stories have been written about the exact subject of how the copyright law is abused to the detriment of creators
