> Saying it is For <group> implies it is not for other groups.
Umm, no? Like I tried to convey in my original comment, "for <group>" means a focus on that group, as opposed to just general content. Nothing I've ever come across that was marketed as "for <>" has ever been intended to exclude me as a non-member, nor have I ever interpreted it that way.
I suspect you have a bias to hear it as exclusionary more than is typical.
Anecdotally, I watch BET fairly regularly, if not often. I'm aware that it's business model is generally content by black creators, for black consumers, but again, I don't remember any hints anywhere of implications of "if you're not black, you can go". If anything, wider viewing would be more informative and promote sharing across groups.
