Same thing with Timnit...was she fired(or "resignation accepted") because of a paper she was writing, or was she fired because of her behavior after being told the paper needed more review(or whatever)?
I really doubt that Google is so wrapped up in the "computer designs chips better than humans" paper that they are firing anyone who sows dissent. A much more parsimonious explanation is the dissenter was welcome to dissent, but behaved in a fireable way after being told other people don't agree with them.
