There are authors starting to publish without a publisher. I think that is the right direction, not making all books free. Maybe once the publishers have less control there will be some copyright reforms to shorten the time it takes to bring works into the public domain. Right now it is 95 years from publishing, but I think the author's life plus 30 years or something might make a bit more sense. For example, George Orwell has been dead for over 70 years, but his works are still under copyright.
