I view that as a positive. Like a lot of other things in the US, the film industry has a long and racist past starting with the infamous "Birth of a Nation," which was highly profitable at the time of its production, but you couldn't make a blatant racist propaganda film like that now, which I'd say is for the better. The article mentions "Borat" which is an interesting example because I'd imagine a lot of people just don't get the joke and would also view it as a racist and anti-semitic film.
