Gina Carano's family have casino money. Her keeping the Disney gig or not will have no real effect on her monetarily. Companies can make you tow the line when you need them, she doesn't.
She's likely been told numerous times, she'll be gone and lose her spin off if she keeps posting comparing herself to holocaust victims and previous posts about Jewish people controlling the world (a few months back I'm pretty sure she posted a Qanon themed meme that depicted Jewish people in this light but can't find it now). Apparently it was Jon Favreau constantly going to bat for her job was why she kept the gig this long. She kept posting because who knows, may be she believes it, maybe she doesn't, maybe she wants to get in on the politics grift instead of acting, who knows.
Conservative, wealthy family, a following, is a 'victim' in her eyes and good looking woman = countless landing zones for her. She's not going to disappear, she'll be on every grifters podcast and show over the next few months and then who knows what she does from there.
Edit: not sure if her post came from Qanon. It was a mural (which was criticised for it's anti-semitism) that was updated to show George Soros etc. Someone grabbed a screen shot of the post here.
There are likely very good people to stand behind that have been 'cancelled' by an online mob for very little. Gina Carano is not that person.
