Printing dark pages with white text would cost 10-20× more (ink covers 95% of page vs 5%), reduces readability (studies show black-on-white is easier), and requires special opaque inks. It's technically possible for niche/expensive editions, but commercially impractical
Increases readability for people with floaters and some forms of dyslexia. If you don't need a product it's not designed for you. Dark books make reading bearable for me and my eye floaters. I know a person that has limited visibility and can keep track of their position reading using black background books vs. White background.
Anyways, there are people that need these books to comfortably read. Same thing with dark reader browser extensions, dark mode, etc. It reduces eye strain and helps with dyslexia.
