I don't know what Ernest is referring to.
We've had this discussion a few times in the last several years, and each time I posted the Amazon Publishing Terms with the critical information. Here it is, again, from the latest of the Amazon website pages - dated 17 Feb 2020. The first link below has the Digital Pricing Page with the Royalties.
https://kdp.amazon.com/en_US/help/topic/G200634500
However, the critical information is buried deep through several links which have weird and changing URLs.
From the Amazon Home page you can select the Self-Publish with us link to go to a page where you can select Publish to Kindle near the bottom of that page you can select KDP Terms and Conditions which opens a new page with a small window which you have to scroll through the long text. You really need to read them all, but the key ones are:
3 Term and Termination which details other sections which continue to be in place after you close your account.
5.1.2 Gives them the right to remove of modify metadata and the cover image for any reason.
5.1.5 gives them the right to reformat the book however they wish.
However, the real killer is 5.5 Grant of Rights which states (bold is added by me):
(quote)
5.5 Grant of Rights. You grant to each Amazon party, throughout the term of this Agreement, a nonexclusive, irrevocable, right and license to print (on-demand and in anticipation of customer demand) and distribute Books, directly and through third-party distributors, in all formats you choose to make available through KDP by all distribution means available. This right includes, without limitation, the right to: (a) reproduce, index and store Books on one or more computer facilities, and reformat, convert and encode Books; (b) display, market, transmit, distribute, sell, license and otherwise make available all or any portion of Books through Amazon Properties (as defined below), for customers and prospective customers to download, access, copy and paste, print, annotate and/or view online and offline, including on portable devices; (c) permit customers to "store" Digital Books that they have purchased from us on servers ("Virtual Storage") and to access and re-download such Digital Books from Virtual Storage from time to time both during and after the term of this Agreement; (d) display and distribute (i) your trademarks and logos in the form you provide them to us or within Books (with such modifications as are necessary to optimize their viewing), and (ii) portions of Books, in each case solely for the purposes of marketing, soliciting and selling Books and related Amazon offerings; (e) use, reproduce, adapt, modify, and distribute, as we determine appropriate, in our sole discretion, any metadata that you provide in connection with Books; and (f) transmit, reproduce and otherwise use (or cause the reformatting, transmission, reproduction, and/or other use of) Books as mere technological incidents to and for the limited purpose of technically enabling the foregoing (e.g., caching to enable display). In addition, you agree that we may permit our affiliates and independent contractors, and our affiliates' independent contractors, to exercise the rights that you grant to us in this Agreement. "Amazon Properties" means any web site, application or online point of presence, on any platform, that is owned or operated by or under license by Amazon or co-branded with Amazon, and any web site, application, device or online point of presence through which any Amazon Properties or products available for sale on them are syndicated, offered, merchandised, advertised or described. You grant us the rights set forth in this Section 5.5 on a worldwide basis; however, if we make available to you a procedure for indicating that you do not have worldwide distribution rights to a Book, then the territory for the sale of that Book will be those territories for which you indicate, through the procedure we provide to you, that you have distribution rights, except as otherwise provided in the Program Policies.

In short, once you upload a book to Amazon they have the legal right to sell that book from now until eternity, even after they or you cancel your account. They also have the right to sell the book to others to sell.
Will they abuse this power is unknown. But it is worrying that they insist on it and all of their sub-companies also insist on having the same rights, while these are rights no regular publisher asks for. The usual assignment of rights in publishing are limited in either time, geography, or both while Amazon insist in having unlimited in all aspects. Some people say they'll never abuse it, but if that was the case, there is no need for it to be there to begin with.
The beauty of going through Lulu is that their terms have the usual publishing limits and not the unlimited ones Amazon ask for. Thus Lulu can not give Amazon unlimited rights they want, and so your rights are protected.

Amazon claims they have 80 to 85% of the ebook market, but the only stats saying that I've seen have all come from either Amazon, other Amazon companies, or have been paid for by them. There is also evidence they totally ignore small owner operator sites that sell ebooks direct from the authors; of which there are a lot.
