Barriers to entry are high for a mobile network, but probably pretty low for a ridesharing app. If Uber and Lyft raised their fares massively, then they're leaving a wide open opportunity for someone else to come and undercut them, even if just for a short time. There might be some 3rd app waiting in the wings to pick up price-sensitive riders and drivers whenever the "cartel" puts prices too high.
