I don't view CNN like Fox News, but it's a cut below my preferred news agencies (NYT, Reuters, AP, NPR, CBS News, Politico, etc) so I steer clear for the most part.
With that said, looking at the two big monitors in the front of the room, I see at least 30 people conferencing in so I wouldn't use this pic as a defining look at diversity. Data shows that black people (and brehs especially) are more likely to WFH when possible. Of course, WFH does lower your chances of recognition (as evidenced in this pic) or potentially promotions in the long term.
