In this so-called shared economy, intermediaries such as Uber, Homejoy, Airbnb, etc. already take a 20% to 30% cut while trying to remain only an app, or technology layer (as they claim when regulators try to intervene). That may or may not be justified. But having yet another app layer take its cut ($100/month!) on top of that seems unbearable. Or maybe bearable just in Silicon Valley.
