I understand the frustration and the anger of authors, and not using KDP may be indeed the sane thing to do for an author. But it appears that the root of these dystopic situations was not an evil overlord, but people trying to use KDP as a SaaS (Scam as a Service) platform [1].
We can still blame Amazon for only catering to the consumer side and effectively ignoring the authors' side.
