This is basically an ad. They forgot to mention that Amazon doesn't sell books, they only rent you a license. It's gone when they want it to be gone. Bookfinder doesn't have this problem...
Amazon does allow authors to make their books DRM-free, with downloads you can copy to any device. There is a partial list of authors here: <a href="https://frequal.com/Perspectives/DrmFreeAuthors.html" rel="nofollow">https://frequal.com/Perspectives/DrmFreeAuthors.html
This is opt-in, so authors self-publishing make the choice when uploading their books.

I don’t see a download option. There used to be one, but they killed it two years ago or so.
And Amazon can still remove the book from your library anytime they want.
