This is utter nonsense. If you looked outside her twitter feed and at evidence, its clear she was fired because she was toxic. Her threat to leave was her own fault which allows google to move forward. Look at her interactions with respected people like lecun. She has issues with disagreeing with people. She may be qualified, she can have opinions, you can also be the best engineer. If you are an asshole when it comes to disagreeing, then no one will want to work with you. Everyone is replaceable.
