Naughty Dog definitely sucks more for orchestrating the whole thing and putting her in the position of showing up to work and finding out she was going to be playing a role for a Black woman if she continued.
The industry sucked for being able to keep roles that secret from people, or being able to work on concepting them until the last minute. Hopefully that’s gonna change.
But all the work with her coach on the accent was for the audition. That’s (unfortunately) unpaid and part of the job. She had maybe signed a contract but she probably hadn’t done any paid work for ND when she showed up on her first day to see Nadine’s design. At that point she hadn’t done the acting work, she could have turned it down and only been out the hours of training and travel to the studio.
The possible PR restrictions is a great point, though.
