If you ever needed proof of the adage that capitalism will co-opt even the most accurate and stinging criticism of it, here it is.
The show was criticized as being racist and so the show appropriated that message (by hiring the "street artists" and instructing them to "go rogue") in order to sell more of the show.
If the producers asked for graffiti, then they certainly got what they paid for. Graffiti has been used as a form of protest and criticism for as long as there has been both paint and walls.
The producers are doing just fine. artistic subversion of commercial considerations is a norm in the arts industry; if anything, this gives an otherwise shallow piece of ideological entertainment some unintended cultural depth.
I'd venture to say this was a pretty calculated move -- no doubt they might not get work with this production company anymore, but they'll surely have quite a few more jobs lined up now with their name out there like this. Also, those jobs might be on projects that more closely align with their political and artistic goals and visions.
I can't speak for the producers, but this would not offend me were I one of them. I'd be quite happy with it.
If I were a producer of the show I might go so far as to actually discuss this issue with the (graffiti) artists on camera, so long as they agreed to be reasonable and collegial about it.
One of the great opportunities for the producers is to shine a light on the show not being particularly racist, but that characters might be - a little.
Having said that, it sounds difficult.
I think the best example of this is The Americans, which stops just short of making the FBI look stupid while kind of raising its eyebrows at the then-prominent "evil empire" narratives. The ...constraints of Soviet political culture are also shown well.
But the craft level of "The Americans" is extremely high.
