tl;dr Books, most likely generated by an LLM, were being sold on Amazon under Jane Friedman’s name. The same books were added to her Goodreads profile. Amazon initially refused to remove the books. If it’s happening to her, it’s definitely happening to other authors.
I was thinking more general of Amazon as in products it sells, rather than only books. Book stores here have been damaged by Chapters/Indigo chains opening up.
