Many of the juicy stories from the book have no supporting evidence other than the claims of the author. Their credibility is all we have to go on here. If someone wrote a message here saying that they were a fly on the wall at the publisher’s office where they had a workshop inventing these stories to sell more books, you’d be right to question their motives.

Even justice system considers the trustworthiness of a witness, evaluating incentive, conflict of interest.

Having worked in another FAANG, I realize a large number of criticisms do come from imaginations, since I could see the contrast first hand. Nobody could tell exactly the consequences of all actions, most of the time it's just a buncha folks trying to figure out what to do, experimenting, iterating. Have you tried executing a conspiracy, like a surprise party? Good luck keeping a secret with more than 5 people.

There's also the problem of perspective. To a less technical engineer who don't know what they don't know, having their deliverable rejected time and again could feel like a conspiracy against them. If you read a blog post from them you'd think the culture is very toxic when everyone is doing their best juggling to be considerate while keeping the quality high.

As with others commenting on this, I've no idea how true the book is, in fact I have never read it. OTOH, even without the book, researches saying social media is making teenagers depress look convincing to me, and, although it's a losing battle, privacy matters a lot to me so I've personally stopped using social media for many years.

None of these give me full confidence to trust nor distrust the narrator, for things that you can't observe externally. It's all percentage.

I think the point is that up until she was fired, she was Meta. She wasn’t a random employee, she was their global public policy director. She wasn’t just implementing policy, she was responsible for creating it.

The question remains whether or not she would have written this book had she not been fired.

It’s not like she quit due to her ethical objections
