Kindle's zero-sum reimbursement for authors means you're probably being gamed.
... the strange universe of Amazon Kindle Unlimited, where authors collaborate and compete to game Amazon’s algorithm. Trademark trolling is just the beginning:...
... unethical marketing and algorithmic tricks are running rampant ...
Authors like Suzan Tisdale, Zoe York, and Margaret Bates expressed the fear that book stuffing as a phenomenon was changing the culture of the genre.

I read 2 pages but still don't know what's going-on. Can someone explain it to me in simple concise language?
In brief, Kindle seems to be a platform which rewards authors for tricking readers. This degrades the quality of their offerings, and makes promoted material suspect.
All greek to me, I'm not in Kindle unlimited, & have no intention of joining.
