People working for a mainstream service like Netflix are wrapped in maintaining their job and catering to white people. Having a separate streaming service with curators from the Black community means more opportunity to express unpopular ideas. This means less Harriet Tubman bios and more current culture/expression.

edit: I should add that having watched a few shows like Jack & Jill (which I had never heard of until now)...I am reminded that when you have white people choose the Black actors/actresses of a show (even if they have Black employees' advice) limits the range of beauty. I forget how many gorgeous people are overlooked because they don't fit the mainstream idea of what "we" are supposed to look like in order to be seen as attractive. It's a subtle thing that permeates our children and culture and really makes a difference in perspective.

Also, the portrayal of middle and upper class Blacks is soooooo limited. I am so tired of hearing about up-and-coming poor Blacks. What about privileged assholes like me who always had a great life with plenty of opportunities? We are out here and we have stories.
