She actually only refers to one specific fact that can be checked -- when Bezos read Remains of the Day. Everything else is just her attempt to re-characterize the environment at Amazon, which is subjective, not factual. (She also has some interesting, though biased, comments on the process of non-fiction writing.)
We need to be careful, as a society, that "everyone has a bias" isn't used as an excuse to discard verifiable information.
