Competition authorities now look at situations that end up uncompetitive, so in this case there is (perhaps implicit, or they are looking for) evidence that its not easy to launch a new phone platform and OS because of the behaviour of the existing platforms. I think the question they need to answer is whether its due to the behaviour of the uncumbents, or that the cost of making a competitive OS (with maps etc) is very high. You could also argue that Android is "price dumping" as it is cross subsidised via the ad business (as is iOS too as Google pays billions) which makes it more complex from the competition point of view.
