Recently Hachette cancelled the novel *Shy Girl*, worried it was written by AI.
I've linked this below, its interesting.
However, I suspect the reason the book has been cancelled has nothing to do with ethics and EVERYTHING to do with the fact that AI work can't be copyrighted.
Publishers are more worried about protecting their moats than they are about the ethics of AI.
BTW, I write this as an author that has been published by Hachette.
