Let's be even more clear - they pushed out someone in their Ethical AI department because she wanted to
have human conversations to determine the basis for being asked to soften critiques.
It's one thing for reviewers, even anonymous reviewers, to reject a paper on its merits; it's another, in Timnit's own words [0], to be told "'it has been decided'" through "a privileged and confidential document to HR" despite clearing the subject matter beforehand. In light of a more general frustration, it's very reasonable for Timnit to escalate the situation by putting her own career on the table, simply to request that people engage with the paper rather than flat-out rejecting it.
And if Jeff wants to respond by immediately cutting ties, and by putting out a document that doesn't even address the situation at hand (edit: much less the underlying issues of unequal treatment for women that Timnit describes)... that's a reflection of his ethics and the ethics of the company that stands behind him.
