This is not an anti-Kindle rant. I have purchased (rented?) several Kindle titles myself.
However, YSK that you are only licensing access to the book from Amazon, you don’t own it like a physical book.
There have been cases where Amazon deletes a title from all devices. (Ironically, one version of “1984” was one such title).

There have also been cases where a customer violated Amazon’s terms of service and lost access to all of their Kindle e-books. Amazon has all the power in this relationship. They can and do change the rules on us lowly peasants from time to time.
Here are the terms of use:

Note, there are indeed ways to download your books and import them into something like Calibre (and remove the DRM from the books). If you do some web searches (and/or search YouTube) you can probably figure it out.
Readarr + calibre makes it very convenient and easy (the rest of the arr suite is great for other forms of media too)
Too bad there’s no easy way for a tech illiterate dumb person such as myself to read a step-by-fucking-step instruction to get it all working for myself.
You basically need 3 things: readarr, a torrent client, and a VPN.
There are plenty of step by step guides and videos for most things, especially popular tools like this. The servarr wiki has install and setup instructions for all of the core arr suite apps as well, both install guides and quick start guides: https://wiki.servarr.com/readarr
Qbittorrent (torrent client) is also easy to install on windows or Linux: https://www.qbittorrent.org/ . You’re also welcome to pick another one, I just like qbittorrent.
Vpn installs vary from vpn to vpn, but pretty much all of them should also contain step by step install instructions
