Assuming Disney+ finds its footing, the stage is set for a Hulu/Disney+ duopoly. Comcast and Disney will starve Netflix, Amazon, et al for popular content, while simultaneously bleeding them on exorbitant license fees for the minimal selection they'll be willing to offer.
Instead of switching between Netflix and Amazon Video, most consumers will switch between Hulu for Comcast-owned content (Universal, NBC, others) and Disney+ for Disney-owned content (Disney, ABC, Fox, Pixar, and many more). Netflix subscriptions will lapse accordingly.
Meet the new boss -- same as the old boss. About the only way this is better for the consumer than the old-school cable setup is that municipalities won't be signing exclusive contracts with cable cos barring any competition for decades-long periods of time.
