I may argue with you there, the drops are public, they aren’t “IP” ... I don’t know the rules for printing in-copyrighted work, but the “Intellectual Property” in this case is the ability to format, translate and print these posts to a book form in a readable format. That takes time and effort and knowledge to me. And if this plan pans out, people will want those books, you should sell them for a profit when the time is right
