Available on Amazon, an exploitative corporation advertising a book most likely commissioned to justify anti-intellectual straw manning. It may have some interesting historically correct but cherry picked facts that wow the reader into Believing this worring narrative. but to blame academia for "cancel culture" is disregarding the progression of humankind and cultural changes that organically occur, and the cyclical nature of how philosophy and culture influence each other.
So should we believe the civil Rights Movement was just the invention of some academic at Harvard? What about the modern influence of big money on information and academia from Murdoch, the Koch bros, Bezoz, Gates and Robert Mercer (bannon's and Trump's main financial backer) which it it willfully ignores. It's easy to get someone clever to write a book enforcing your world view if you have enough money. This is just revisionist anti-intellectualism.
I'm sorry if you think this book is proof of anything to do with what's happening now culturally but it not.
Oh look it got a rave reviews from the right wing Tory rag The Tmes and The financial Times. Are we really this naive? Please try reading a real review of the book instead of the paid ones and sycophantic far right conclusion shoppers.
