Kindle Unlimited has other problems that make issues for content quality, king among them being the KDP Select requirement.
I’ve managed to find value from Kindle Unlimited, but pretty much nobody but self published authors (which I have no problem with, but there’s effectively zero bar to entry meaning quality is over the place) is available on the service because of the KDP Select issue. It doesn’t seem to be evenly enforced either, since the Harry Potter books are available via Kindle Unlimited yet are available for sale on other eBook stores, for example.
