Timnit Gebru was fired from Google after threatening to quit unless Google reveled the identities of the reviewers of her paper that was not received well while accusing them of sex/race based discrimination.
You can find some of the experiences of her from previous colleagues. You'll find the toxicity that she used in her time there and how she is picking the race/sex card on every situation. This is likely a continuation of that.
Not that the allegations can't be true, but people like this are really diluting the message and making it hard to tell the legitimate from exaggerated hit pieces.
