>This is a streaming service set up to elevate content by black creators, to make up for the fact that the mainstream media under-represents those people. I'm struggling to see the outrage on a cultural level and on a startup level I can absolutely imagine there is a market for this.

If you find any niche that makes sense, go for it. There's a reason for MotorTrend to shift into cable and on-demand, Disney, etc. The market can get slice 'n diced in a million ways from the Left Handed Channel to TrannyTV (for transmission specialists naturally).

>make you think about the ways in which Netflix does not serve black people.

Heck, it (Netflix) doesn't serve me, and I ain't black. It's a pity that they can't run out and buy rights to a jillion older movies, but I guess everyone is still loathe to license them (or too expensive).
