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...
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.
And if a book is on the no DRM list you can find a "download" link in the drop down menu for the book.
But I have not found a way to determine if a book has this option before buying it. So I'm not longer buying anything on Amazon.

I have many fond memories of sharing games as a kid with my friends. Of renting them from Blockbuster. But nowadays it with everything digital…that’s all gone..
