Instead, small authors who self-publish and give Amazon exclusivity, I'm entitled to 40% of the proceed of the book. For basically access to the marketplace. If you go to some authors discord and make small donation (often half of Amazon's price), they'll send you drm-free ebooks. That's what you should do if you really want to support author and dislike markup from marketplace monopolies.
