>Shouldn't they be rewarded for taking that risk? In a market economy, popularising a concept and taking risk should only be rewarded to the degree that it gives you a headstart over the competition. That reward should peter out over time as new competitors enter the market. If the market structure (for whatever reason) turns out to be such that new competitors can no longer enter the market then that is a dysfunctional market that doesn't serve its purpose. Clearly the network effects that govern operating systems are so strong that the likelihood of new market entrants is extremely low. App stores don't compete on merit. They derive their pricing power from the fact that market forces have ceased to exist. So the question is whether we should allow the handful of companies that dominate operating systems at any given point in time to leverage that power to set prices in related markets without any restriction. At what point does that result in rent seeking that frustrates risk taking and innovation?
