That's still extremely anti-competitive. Incumbents are in an much better position to pay large sums of money to have relatively minor services stream for free. People will flock to those services and a small competitor will have no viable option of paying for the fees and remaining profitable.

You might counter that with "get funding!" But I think the internet is amazing because of it's low barrier to entry. Blocking that might not prevent "disruption" from startups, but it sure as hell will prevent many people from casually trying things.
