Does it also require a certain intellectual integrity to do properly?
Because claiming that you were "immediately fired" online, then later having to "clarify" that you actually submitted your resignation because some demands weren't met sounds pretty dishonest to me.
As a result, we are accepting your resignation immediately, effective today.

Looks like Timnit Gebru made an ultimatum and offered her resignation if the terms of the ultimatum were not met. Google accepted her resignation and chose to have it effective immediately (as is often the case when you resign and a company feels like it would not be beneficial to have a longer departure period).
It's not like I'm taking only the words of others. I'm reading what Gebru herself chose to put out there.
That is the language used when firing someone for their behavior.
However, we have context. We know that an ultimatum including a resignation threat was given.
Accepting that resignation and making the termination of their employment relationship immediate with some extra "Yeah, this is for the best" language doesn't mean that she was fired.
If you only want to consider the limited context of ignoring that she submitted a resignation ultimatum, aren't you just cherry picking?
