So what? I think, if you read a good book, learn something or are well-entertained, it's a positive externality, so there is no problem with people doing it for free.
The only real issue with IP piracy is when someone gets money by copying the works. Which were originally the cases copyright tried to prevent.
Maybe you can clarify why you see people doing these things for free a problem, when there is a net benefit to society and also you.
