But Appoogle together clearly form a duopoly that does have monopoly power over the market. And they both charge 30% to App devs for the privilege of selling Apps on their respective platforms: coincidence or price collusion? Well it certainly looks like collusion from where I'm sitting. (Yes, yes: Apple has just cut the rate for small devs. The big sellers still have to pay 30% though.)
