Well of course the editor and writer want to fill space with stuff that sells. That is, after all, the point of the art. But I'll tell you what I think. I think the writer is at best stretching the truth if/when she asserts "much of the voluminous response is hate mail."
I believe she is mischaracterizing the response, in order to justify her original critique. She has not changed her position.
I agree with your point that it's a story in itself. But if her follow-up story is to be taken seriously, as more than "piling on," she needs to serve up more than vague whining.
