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.
It depends. I’m not saying I never pirate books. I’m not going to just support a publisher milking a book that should belong to the commons.
Also, some publishers have taken to raising ebook prices to as high or higher than hardback costs. For those I might buy one book by an author and pirate another. I won’t justify it other than to say I only ever bought paperbacks anyway and still remember those being like $3.99 to $6.99, so I’m not paying $18+ for an ebook novel because of publisher greed.
But if it’s an author I like, I buy their books, and support them in other ways (like with Sanderson’s Kickstarter for example).
