I'm responding narrowly to the subthread here, which is about firing someone who gives an ultimatum in the abstract. I don't know enough about the specifics of Timnit/Google's situation to pass judgment. (I'm also an employee there, so doing so would be unwise and a potential violation of confidentiality rules if I did know anything.) To me I'm filing it under "Everybody sees through their emotions, and different people will have different perceptions of what actually happened and what people actually intended."
