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.
My understanding is a lot of those were just wrappers for mobi files to add even more drm, but I haven’t looked super closely.
I dunno. I used to be super hardcore about ripping every book and putting it in my calibre library. Then I eventually realized that… mostly I don’t care. There are very few books I am going to re-read and the majority of those were so good that I either want the hardcover to put on a shelf or don’t mind buying again from a vendor that gives the author a better percentage.
Yeah. In my case, though, a lot of my library consists of relatively expensive reference works that I use regularly and that would be prohibitive to replace if Amazon decided to play games with them.
