It's also not entirely accurate to say she was fired. Lucasfilm's statement was that she is not presently employed by them, and there were no plans for her to be in the known future. She had already finished filming season 2 of The Mandalorian, and -- even if she was part of it, which was only contextual rumor -- filming hadn't started on Rangers of the New Republic. So she was not terminated from a job she presently had. She had finished one gig, and likely won't get another from that company.
