Not sure you can call it censorship if it's the author of the book who doesn't want you to access it for free. I know there are a few levels of indirection here, but with a few notable exceptions authors are normally against their books being pirated. I personally sure want Anna's Archive staying up, but comparing it to nazis burning books is a bit too much IMO
