If I'm a writer of fiction, you are not automatically entitled to my novel, into which I expended an enormous amount of effort and time. You're expected to pay a fair price for it. If you demand "free" entertainment, write it yourself!
If I'm a textbook author, "information" does not "want to be free". There's a huge distinction between knowledge and information. Knowledge is "out there"; you're free to collect it by yourself. Information is my interpretation of that knowledge, structured and packaged into a book. Information is not free. You are not entitled to the product of my labor - pay fairly for it, please!
Note this this post is not about publishers, but authors: the originators of creative thought and structured information. You do not have a right to that work without a fair exchange.
