The fact Johansson did not give permission to OpenAI to use their voice, they then hired a voice actor to similarly copy her voice likeliness with Altman tweeting a reference to the film ‘Her’ which Johansson was the starring voice actor in that film, tells you that OpenAI intended to clone and use her voice even without permission.
OpenAI HAD to pull the voice down to not risk yet another lawsuit.
The parent comment clearly has the weakest defense I have seen on this discussion.
