I can see her telling them off as well.
For one thing, she's not really from "Hollywood". MMA fighters tend to be less likely to take being *expletive deleted*it than struggling actors. I guess it would depend on what they offered her and how much she liked Star Wars.
On the flip side, after all this, if she ever does any Star Wars again at all, it's clearly a win for her. They dumped her, didn't tell her and let her find out on social media, then came crawling back. No way to spin that, although I'm sure Lucasfilm would try.
