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.
