I'm not really sure what she thought was going to happen. There is no way that Musk was going to stop making decisions, especially about content moderation, which is really the main concern of advertisers. If he wants it to be his kind of speech over the concerns of advertisers, that's what it's going to be, and she has no path to success.

I've heard Elon really seems like he's listening and that he's actually going to take advice. Yoel Roth actually believed that Elon was going to implement his trust and safety recommendations. Then he would go and tweet what he was actually going to do as soon as he was out of the meeting. At this point it's pretty well documented.
