Does he have to acknowledge it to us? Isn’t his mental health private? It’s inappropriate to say he has to broadcast that.
This is what I found on Wiki, “On February 3, 2006, Chappelle made his first television interview since production ceased on season three, on The Oprah Winfrey Show. He stated that burnout, losing his creative control, and a work environment that was uncomfortable, were some of the reasons he left the show. He also stated that he would be open to producing the remainder of season three (and perhaps a season four) only if his demands were met, one of which was to ensure that half of the proceeds of future Chappelle's Show DVD sales would go to charity. Chappelle claimed that if Comedy Central aired the unaired episodes, the show would be finished. After that announcement, Comedy Central stopped advertising the release of the third season for a period of time.”
Wow, he comes off like such a greedy asshole here. /s
