Netflix's dominance is a byproduct of the content spend, that's the flywheel. Netflix can spend more because of its overwhelming scale(fixed costs are distributed between more subs), and subs gets amazing value because there is so much content
I think Netflix's policy makes sense, but it isn't really important so I don't want to dwell on it
That's simple. because Netflix is the only globally scaled player it has a significant economic advantage on everybody else. the marginal content cost per sub is much lower for Netflix
Company A has 10,000 subs and spends $1M on content, it needs to charge each sub $100 to breakeven.
from the consumer perspective he has to choose between paying company A $100 and get $1M of content or paying $10 to company B and get 10x the amount of content.
Netflix is not dependent on content providers for licensed content, it's the other way around. I already touched on it in the linked Friends thread
because video is differentiated and the experience is not very personal, the market will probably be able to support multiple players at maturity. the ability to raise prices will depend on the value offering
