Do what I do: buy another print copy and give it away to a public library. Then download the ebook version from the darknet.
This achieves several things:
- You bought a copy of the book, so your money goes to the author... well whatever measly sum the publisher gives them, but still. Your conscience is clear.
- You have the ebook version, yay!
- You're doing a good deed by donating books to a library. Not everyone can afford to buy new books.
