It should be scandalous in those cases too. Having a company be both the distributor and producer and have a monopoly is problematic. This is sort of the problem of cable TV also, where companies like comcast tries to be a producer and distriutor and have a monopoly. In the past we have had unions fight against this sort of thing but unions have been busted to hell in this country over the last few decades to the point where even smart people don't even understand why its bad for a company like amazon to do this, we don't remember why.
Your argument may have held weight in the past, but now, anyone can distribute video without going through the cable providers regular cable distribution. It’s quite simple technically to provide on demand video at scale, including creating apps for all the platforms. The only issue now is when/if cable companies as internet providers start deprioritizing competitors.
