well there's a saying about evil flourishing only because people stay silent etc, so by not doing or saying anything, even after they'd signed whatever you needed from them it could be said you were ok w/ their actions.
the chinese and Japanese industries are huge. as an argument, would a "low profile" Chinese actress do better under her own name in her own country's industry, than as a low-profile actress in Hollywood? wouldn't there be a better chance for her to rise up the ranks and become a big start there and then maybe carry weight in other countries? look at Jackie Chan or Chow Yun-Fat as examples, unknown over here except to fanboys but absolutely colossal stars in their own industries.
frankly, my own perception is she's not breaking down those barriers, she's just whoring her beliefs in an attempt to make money. there are plenty other places to make films [or TV], she just wants to be famous and rich so she's not willing to back up her standards and walk away from an industry she says is highly racist against her race. But as i said, i don't fully understand her cos the gist seems to be they don't like her name but are ok w/ her looks and abilities, so i'm not sure where racism comes into that; i always thought actors applied using a demo reel or at least a resume w/ head shots etc, so i don't know if the name would be the only factors. and expanding on that, if the studio thinks [or knows, from past experience] that "John PAtel" on a poster will not put bums on seats that way "John Smith" might, are they being racist by casting to protect their profits? or is the fault at the audience's prejudices at that point?
