Separate from Clanchy, Goodreads isn’t a space for honest reviews and there have been plenty of purposefully hostile reviews left (say, for gender critical books) designed to bring an author down. Goodreads is a huge problem for publishing. Book bloggers can cause huge problems especially since the Society of Authors decided to class them as authors and allow them to join, causing no end of problems.
The reason the Clanchy story matters to women is because it mirrors so much of what happens within the book industry to gender critical authors. For example, when Rachel Rooney did a SAR for her publisher, as in this case, her publisher redacted every word that wasn’t her name. Every. Single. Word. That also involved a badly behaved publicist.
Rachel and other writers, especially in children’s publishing, have faced huge hostility and bullying from other writers as with this case (and sometimes involving the same women, who are, surprise surprise, TRAs). They have faced hostility from within their publisher.
Whether you like KC and/or her book isn’t the key point. It’s how her publisher and the industry behaved that matters.
