This is perfectly reasonable fair use.

I'm starting to realize that a lot of content creators either don't understand fair use, or otherwise are unreasonable control freaks.

Well thats questionable actually

Sure the _result_ is transformative, but it had to consume the content in the first place to make a transformative. (grey area).

Yes, you _could_ argue that its a plain review, but you need to prove that its actually reviewing it rather than just quoting. But as its the machine doing it, that further muddies the water. Is it the end user whos generating the review? does the kindle license actually allow them to do that?

However, the other thing to note is that there is a contract between publishers and amazon that go over and above copyright. It will say how and where works can be distributed and how they can be processed. For example you're not able to distribute the book and then create your own audiobook version of it.
