On Feb. 26, 2025 Amazon will remove your ability to download your ebooks to your computer or any other device except Kindle. (crosspost from !bookclub)
If you have books on Amazon and you want them to be on any device besides Kindle, download them soon.
As an alternative Kobo offers price matching and carries almost all of the same books minus some indie exclusives (which is a huge shame, there are some good indie book series I guess I won’t be finishing)
You go to your Amazon account to find your book purchases. You can still load the books onto kindle, but nowhere else, so you're locked in to the kindle ecosystem. The guy in the video explains it better than i can.
