Given that, at least in Timnit's narrative, the email included a request to discuss the issue in person when she returned from vacation, I don't think that the "ultimatum" characterization is uncontroversially accurate for the immediate case.
There’s tons of issues I wouldn’t compromise on, and better leave the company if I had to. Does that mean I’ll be fired the very second these subjects become remotely relevant and/if I make clear where my boundaries are ?
"X is the lowest price I can sell for, take it or leave it" "How about X-10?" "Done"
"I want to read 5 books!" "You can either read one book before bedtime or go to bed now" "How about 2 books?" "Okay, but then straight to bed!"
Putting the ultimatum in e-mail form really raises the stakes, because there may be other people CC-ed or BCC-ed, and any response could later be weaponized.
If the relationship was already troubled, anything like an ultimatum is an opportunity for the manager to be rid of all their troubles.
The level of the threat also comes into play, and more severe threats increase the risk/tension. If the guardian had threatened to disown the child rather than send them to bed, we would read the situation differently.
They way this was handled doesn't make any of the involved parties look good.
The narratives from the participants on the actual communication differ on key points relevant to evaluating whether it was really an ultimatum.
"Tuesday Gebru emailed back offering a deal: If she received a full explanation of what happened, and the research team met with management to agree on a process for fair handling of future research, she would remove her name from the paper. If not, she would arrange to depart the company at a later date, leaving her free to publish the paper without the company’s affiliation."
I read that as an explicit ultimatum.
