What you're describing is competition. It is an entire industry on content creators selling their creations to the highest bidder. The thing that streaming enabled was for the small documentary filmmaker to sell their work to a large studio (family member did just this). I don't think it's their fault that their is ALSO intense competition above them in the stack, which is what you're saying is the bad experience.
You're arguing there is TOO MUCH competition not too little and that a centralizing force needs to help improve consumer experience. Fair, but not your original point.
