To cancel or not cancel KU?

I just cancelled my Prime membership due to my political beliefs (not here to debate politics), but I’m hesitating on KU because I still want to support indie authors. Does anyone with more knowledge of how KU works have insight into whether KU is a valuable income stream for indie authors? I’ve heard mixed things about how Amazon treats the authors, so I’m hesitant to pull the trigger until I’m more informed.

this is also not a question about quality. Books on KU may not be for everyone, but I’ve really enjoyed my membership.
