I can't help but feel like everyone commenting here read the headline, brushed straight past the lengthy explanation and went directly to outrage in the comment box.
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.
I'm going to guess that "Netflix for black people" is not going to be the tagline the business will advertise itself on, it was chosen by an early-stage startup to catch your eye and make you think about the ways in which Netflix does not serve black people.
