GNOME-based Linux distributions ship with DjVu support by default, and so do MATE and KDE and most document viewers for Android. But even if you're not using Linux, if you're going to spend 50 hours studying a textbook and you're part of a learning community like a university class, with dozens of people facing the same problem, one of you can spend 0.5 hours figuring out how to install DjView so you can read the textbook. That's a much easier problem to solve than finding out about Library Genesis in the first place, not to mention fixing your legal system so it's legal.
