We would have no book if the author was a hero: they would say "I'm not doing this," quit, and that would be the end of it. By this definition, only an unheroic person could've written it. By the same definition, an firsthand expose of Meta could never be written by a trustworthy person.
This obviously protects the company: you are ceding this ground to them, "No trustworthy person could work at your company and write an expose." I don't think we should cede that to them.
GP's point is not that only heroes should tell the tale, but rather that in this case the whistleblower was also an active part of the problem, but sought to distance herself from her then behavior by swapping it down instead for a more passive lack of situational awereness. That is, she reached for stupidity as an escape hatch from having to reckon with her own malice. And she's now being celebrated for it.
The lack of accountability paired with the celebration of the "hero" are the problem. Not the fact of her testimony.
EDIT: Some people who have similarly testified acknowledged the part they played in the situation they later denounced. So, it is possible for the story to be told and for the teller to also say "I knew what was up. I said nothing. I did nothing. I'm sorry."
Not really. Author could have whistleblown and quit early on revealing unsavory things.
The book is mainly attempts to embarass Zuck (eg, he’s sweaty, he’s not good at Catan, etc).
Why is it that the only people willing to testify against the cartel are murderers, drug dealers, and bank robbers? These are not trustworthy witnesses.
Same problem.
