Whataboutism doesn't justify anything. There are quite a few nuances. For example that Android and iOS have way higher adoption numbers than game consoles, and that these OSes play a crucial role in people's everyday lives. In addition, do these platforms have a duopoly, so perfect competition doesn't exist on that level, and like elboomy states, does Apple have a monopoly on its own platform. Apple forcing a piece of the cake is thus merely a power play which is enabled by the imperfect market of smartphone OSes and their app stores.
