I've yet to run into an Amazon-purchased book that Calibre can't liberate, and I haven't even updated Calibre since installing it a few years back. Where are you seeing this turn up? If I need to be looking for alternate sellers or finding some workaround, better to know it ahead of time, I suppose.

KFX just started rolling out in recent months.

As the parent post said, the only way right now to "crack" is to dodge it. To have Amazon send you a copy of your book for a older device or older version of the PC software that doesn't support KFX, so they have to send you a crackable format instead.

I haven't done anything with Barnes & Noble in quite some time, but I've been curious to try a eBook purchase from there to see if their current DRM is any more friendly.

That explains why I haven't seen it! I haven't updated Kindle for PC in years, either.

Thanks for the info! I might have to give B&N a try myself, although at the moment the only books on my list are preordered.

Most of the DRM removal tools are based on Apprentice Alf's DeDRM library. Here's the Github issue related to KFX:

Does this mean if you used kindle unlimited you could effectively keep the books forever?

If you are going to pirate the book, you might as well just go straight to something like Pirates Bay. It's much easier.

Very many books are not available on torrent sites.

Very many are available on library genesis among others. The pirate bay is a bad place for books.

As mentioned just up thread, if you don't purchase in the most recent KFX DRM format, you can strip the DRM. However AFAIK this is illegal to do for Kindle Unlimited ebooks. You are not supposed to keep them, just borrow.
