If YouTube can't make the margins I don't see how it could level the playing field for smaller companies to compete.
What a depressing statement. So there's no value in having a diversity of choice, points of view, taste, etc? Or in allowing anyone to share what they've made, without gatekeepers? Do you only listen to the top handful of musicians, or read the top handful of books? Hell, HN is not in the top handful of sites with the vast majority of revenue and views, does that mean it has no value?
I'd say it's actually the only value it has; it's what distinguishes it from TV, which is otherwise a better system in other ways.
Every channel started with 0 subscribers once and were part of that "400 hours of video uploaded every minute".
