I do wish all artists had a donate page. Most do not.
How much of that money goes to the author instead of amazon?
Why’s that relevant? The payment is divided by the terms of the agreement with the author and associates. It was mutually agreed by everyone in writing.
How could it not be? I want to pay the creators, not some useless middlemen who only exist to solve the problems created by copyright.
Not the customer. Should they be able to pirate/donate and feel ethically okay?
