Not parent poster, and you’re totally correct… But paper-format books don’t work at all for me, or many others with accessibility needs. I read almost exclusively with TTS while driving/doing chores/walking or to fall asleep. It’s… very hard to TTS a paper book.

So, an old (<= 5th gen) Kindle works great. They’re incompatible with the newest Kindle DRM, so they still allow old methods to transfer books. For KU books, it also has built-in TTS, so you can leave the book “reading” for you after you’ve transferred the file to your “real” device. That way authors get paid for your page reads, but you can still read/store/transfer/preserve the book.

But Amazon still tracks your reading data, and you’re still supporting Amazon’s/Kindle’s self publishing monopoly… But it’s literally the only place where books from my genre of choice are available, so not really any good options until their unethical monopoly is regulated away from them.
