I, too, am VERY unhappy with KU but was afraid to voice what I really felt...until now. From the minute it began my sales dropped like big rocks. I pulled out of it on 4 of my books after the first two weeks, but my sales never recovered. What makes it really hard for me is that for over 30 years I was with legacy publishers (15 novels since 1984) and NEVER made a living at it with 4%-18% royalties and having no power or say in what the publishers did with my work. I worked extremely hard on my novels and literally gave up my life to create them. I suffered all those long years either working full time out of the home at graphic arts jobs plus writing on the side or I starved. But I never gave up, praying that one day my books would earn me what they deserved. A modest living. I write horror, but my life because of the greed of publishers was a horror show in itself. THEN I discovered Amazon KDP and self-publishing in 2012 and self-published 6 of my books with them - AND FOR THE FIRST TIME EVER I WAS MAKING GOOD MONEY! I was thrilled. So this sudden loss of income again just when I'd started getting it hurts even more. I, too, have spread my books to other venues, but, of course, the income is nowhere near what Amazon used to pay me.
To tell the truth, from the very beginning I thought that KU was just another way to effectively lower our royalties or prices on eBooks and the final insult was that 10% reading thing...I have lots of eBooks on my Kindle I got free and STILL haven't started them. As I see it KU will NEVER work (for us novelists who write full novels). Hey, I feel like I was giving away my books for almost free for over 30 years...and now if I stay in KU, I'll be doing the same thing. Does Amazon want to become a legacy publisher like we all are fleeing from and they seem to disapprove of? Because, in my opinion, they're doing a good job of recreating that whole unfair bogus system where they make the money and we authors survive on the pennies that are left. Please Amazon...reconsider KU and get rid of it!
