> Really makes one wonder if this document is one that Google does not want to come out in discovery, ever, and that it's in some system with a relatively short TTL before it gets deleted, because policy.

I suspect not, because it's probably a carefully constructed document to fit the pretextual narrative of the constructive termination campaign that it was part of, which was targeting Gebru based not on the particular paper but on race/sex and criticism around the internal culture on those issues.

At least, it's pretty clear to me from all the Google AI people describing how Dean’s characterization of the review process does not comport with the usual practice of that process, and in some way differs from even the official documented process, suggests very strongly that the entire review issue was pretextual and personally targeted, and not about the paper itself at all. The interpretation of what is behind that pretext is a little more speculative, but you don't need a pretextual campaign unless the actual basis is prohibited or even worse for PR than the pretext.
