"Starting on February 26th, 2025, Amazon is removing a feature from its website allowing you to download purchased books to a computer…
It doesn’t happen frequently, but as Good e-Reader points out, Amazon has occasionally removed books from its online store and remotely deleted them from Kindles or edited titles and re-uploaded new copies to its e-readers… It’s a reminder that you don’t actually own much of the digital content you consume, and without the ability to back up copies of ebooks, you could lose them entirely if they’re banned and removed."
