That could be part of it but I'm not sure it comes close for most ebooks. A lot of these books are professionally typeset and laid out pdfs, not sloppy calibre conversion pdfs. I don't think Amazon sells in pdf. As far as bounty forums, I just looked at one site over the last three days. It averaged 365 books per day, 199 per day with 2023 publication dates. That seems like a lot of successful bounties!
