On the 'cheating' point, the latest figure I could find for the Irish Public Lending Right payments was 4.39 euro cents per loan as of November 2020. [1]
The latest KU payment information I could find for the UK was from September 2020 and was GBP£0.0032 per page. [2] I'm not sure how that would compare to the Irish rate, so I'll assume it is the same.
Converting that to euro, that is 0.3561 euro cents per page.
So as long as someone reads more than 12 pages of your book through KU, you would be paid
more than if a paper copy had been borrowed through a public library. If someone reads a 123 page book in full, you would be paid
10 times as much as the PLR would have paid out.
How exactly is this a massive scam whereby Amazon is cheating authors?
I've double-checked these figures, as I didn't believe the results and assumed I was off by a factor of 10 here, so please shout at me if you spot a mistake.
