It&#x27;s also about having a means for giving a legal smackdown on Holocaust denialists who are itching for the material to come out of copyright so they can chop it up to produce their own material.<p>That&#x27;s also why Disney does everything they can to keep copyright on works they explicitly do not allow to be displayed outside their control. For example, &quot;Song of the South&quot; is a huge embarrassment for Disney, and the copyright means they can allow only scholars to exhibit the whole movie.<p>They&#x27;re still wrong to do it, but it&#x27;s not just about the money.
