This is literally equality. Half white, half POC cast. They're giving everybody an equal opportunity to win.
People of color have been getting the short end of the stick now for 22 seasons, because the majority of the cast has always been white, and in turn vote out all the people of color as soon as they can and for 21 seasons we've gotten a white winner because of it. It's time to level the playing field. Maybe we'll continue to get white winners (most likely), but at least they're trying to be more diverse.
