This has nothing to do with power. This is simply about a contract. Dave messed up by not signing his new deal or negotiating royalties for future platforms.
Dave is the one being hurt by all of this as Comedy Central been replaced him. Key and Peele set their contract up correctly. They have both went on to create their own brand and business outside of Comedy Central.

@tallblacknyc said earlier, Comedy Central will just sit on this show for a few years and release it again. I feel for Dave but he either needs to move on or buy back the show
