Actors aren't just paid to act, you know.
They're also paid to do whatever they can to draw in viewers, which is why they do press and appear on talk shows. That's a well-known part of the job, and actors who won't do publicity miss out on a lot of offers, and refraining from driving away viewers is also a well-known part of the job. Especially if an actor has a long-term contract with Disney! They are known to be control freaks about publicity and to try to make their actors follow the company line in public.
Carano has been very foolish through all of this. Not for shooting her mouth off, which nobody can stop her from doing, but for shooting her mouth off while working for *Disney*, and doing so while playing a role where she could be written out at any time with no change in the show. Sure, I liked her character, but she's just someone Mando sees now and then. If he doesn't see her again, well, it's not like she was important to him.
