In his model the whales don't really care what they vote on, they're just trying to maximize their rewards. The money at stake is large enough that personal preferences of whales fall by the wayside and instead they will be forced to serve the market by the need to stay competitive in return-on-investment. (In fact some whales may -- even today, but certainly in the future -- be businesses or collaborations that don't even have individual personal preferences.)If the minnows and dolphins vote on what they they like, the whales will follow.
