More particularly, there may not currently be a way to remove Amazon's kindle crypto since an update in 2019 I think. I'm not positive, but I recall reading that.

Me, I just refuse to buy the books from sellers that cruft them with DRM. And I'll tell any author that. I've been an avid reader of some authors and I've stopped buying their books because of how they are electronically distributed/enrcypted/managed. Vendor lock-in is a very bad idea. Several very rich folks have had shots at Apple over that issue related to music libraries and not being able to transfer them to their kids.

With a real book, I can give it away, I can sell it, I can share it. But I wouldn't with authors I buy and read because I want them to be encouraged to write more. The most I'd ever do is lend one to someone so they can see how the writer writes and then most of the time, I create a new reader who will buy their products by doing that. Smart authors know that.
