Isn't that the main thing this thread was about, in the beginning? The effect this kind of thing has on authors and publishing?
If you look at all the memoires and essays and reflections etc published from 1920 until now, KC's book is pretty mild, even if you don't like the things she said. And plenty of people think what she said is just fine for the kind of book it is.
If you look at all the bad behaviour of authors over the years, this particular debacle is pretty low key - some bad judgement and a little too proud maybe to back down. It's not difficult to think of a great many authors who have been worse (not to mention other kinds of celebrities.)
Combine that with the kinds of problems we all know authors have been having in terms of publishing books that are either controversial, or don't tick all the right boxes, or cases where authors are being told they can't write about certain people, very fraught and obscure "rules" for describing people.
That's not a healthy publishing industry and as a reader it's no bloody wonder so much that comes out now is insipid and pointless.
