because he wasn't rewarded enough

That's because the reward pool just plain isn't nearly big enough to compete with revenue share that comes from selling advertisements, even if all of it went to successful youtubers. Trying to come up with ways to direct more rewards to that sort of thing is ultimately futile and prevents the reward pool from being useful for cases where it is practical, like encouraging new users who aren't famous and appreciate even modest rewards as being more than what they get on most free sites.

If you want to compete with youtube, you need a business model that attracts outside revenue, e.g. from advertising, which scales with viewership and then directs that revenue to creators. The Steem reward pool isn't that and can't be that.
