He's wrong about paperback, they're a gold mine for authors. Halving the price doesn't multiply the number of purchases by 2, it multiplies it by 20. That's why ebooks outsell hardcovers on Amazon but are still a trivial fraction of overall rev. Also, it is not any more work for the author. You usually don't even have to sign any additional paperwork. It's extra work for the publisher to be sure, but it's all gravy for you.
