For me, the primary takeaway from this article is the absurdity of copyright lifetimes that keep a book published in 1947 out of the public domain, printing money for people who had no part in creating it.
I feel like the time is ripe to change that. It used to be that copyrights were held by big corporations and small enterprises were the ones who wanted to infringe. Now copyrights are held by millions of users and big corporations like Google and Facebook want to make money off that content. They could lobby for a major change to copyright law.
