I have followed this quite closely as it is my field, and I think you’ve misunderstood, OP.
The issues around Clanchy’s book are:
She denied accurate quotes from her book were in there, and launched a coordinated attack on two women of colour who had respectfully drawn attention to them
She was supported by her publisher and the mainstream press to defend herself, while the women who had tried to open a debate were harassed, abused and - yes - cancelled.
Clanchy did not apologise for anything in the book but it was withdrawn by her publishers for an edit.
There has been a slow, grassroots movement (chiefly among feminists) ongoing for many months to support the women who have been victims of this abuse. It is not the first time that Clanchy has been implicated in this kind of campaign against less powerful writers
In the last few weeks, the publishing industry has started to listen more to these womens’ voices. I see that as a victory for feminism.
The issues around the racism and othering in the book are a valid but separate issue to these issues of bullying and racism. Although having said that, there is a link - to do with the relative power and behaviour that middle class while women can have in some contexts, and how the ideas of feminism can be misused to defend indefensible behaviour.
I am myself a middle class white woman who works in publishing, and a fan of clanchy’s work, this has been a very horrible time but I do believe the publishers have made the right decisions. I don’t think Clanchy has been cancelled, so much as held to account.
