She said, "If you can't meet these conditions, I will resign effective <XY date>." Google said, "We can't meet these conditions, we accept your resignation and move it to <much earlier date>."
People will have to find the source document, which to the best of my knowledge is not public (note, not the message to Women and Allies), read it, and then reach their own conclusions.
I stand by my characterization. She characterizes it herself thusly:
"I said here are the conditions. If you can meet them great I’ll take my name off this paper, if not then I can work on a last date."
I think this is a major source of confusion in this whole conversation. There is clearly a follow up conversation between Timnit and some manager(s) (the name Megan is mentioned) in which this ultimatum was proffered.
