As a black person, we have seen many many a show that features us, get ripped off the air, even with good ratings.
Fox did that. Then they replaced it with move race dividing shows.
You see, they don't want us all watching the same shows. One day at a time for example, was an attempt at getting a Latino audience so as to use that audience to show commercials to them. Raising Dion, same thing, but for blacks.
When the audience doesn't get divided into pockets good enough to reach the wanted demographic, it's going off the air. Music genres are the same way. Disco, and smooth jazz were examples.
Those genres were swapped out for something more polarized, like a Spanish speaking station, Republican talk radio, sports talk, etc.
The other problem was, the use of blacks as a lead to introduce LGBT people and make an LGBT show, and Netflix now sees that doing that common trick, doesn't lead to a large liberal demographic as they might hope, and when they introduce the LGBT person, the ratings plummet. They cannot openly say this because of backlash.
