We're comparing two different companies here. Netflix et al, are in the business of producing original content (good for them), while YouTube et al are in the business of serving user-generated content.
That's not a bug, but a feature. Its the same difference as a high end restaurant, and a hole in the wall restaurant. Both are serving food, yes, but they are doing business in different categories. You cant go to the second restaurant and be like, the food you served didn't come with a smile like this other restaurant here. They seem to have figured it out, why cant you.
Or similarly, you cant go to the high end restaurant and be like - you charge for water now? Why cant you be like this other hole-in-the-wall restaurant.
