Good point, you raise a valid downside possibility to this approach. The ecosystem could in a sense become less democratic and it becomes harder for the little guy to succeed.
It's a question of what the goal is, I suppose. If the goal is to make this thing as big as possible and disrupt the existing networks, this approach might make sense. If the goal is to keep it as democratic as possible, it likely makes sense to keep the current incentive system as is.
