French people of African descent are not culturally the same as American Black people. Black culture is unique in that it was created artificially by kidnapping millions of people from the African content and stripping them of their cultures, family ties, and names, prompting those people to construct a new culture (while uniting them for another 100 years in the experience of apartheid and the civil rights movement). It's its own powerful, interesting thing.
But, of course, there are TV stations for all sorts of ethnicities all over the world, so the answer to your question is just "nobody would care except message board trolls".

I don't think my point is "no other group of people has endured what Black people have". At any rate: I don't think I have much more to say about this that would be relevant to Uzo and Iyanu's startup, which is neat and deserves the attention.
