For people saying this is just the iPhone and I can always buy from a different OEM, it's not about my individual choice. Say I am a mobile bank or some other kind of service that needs to reach all my customers on mobile. There are significant populations across the world on iPhone, so to stay competitive as something like a challenger bank, ignoring iOS is simply not an option. If the argument is that Apple provides payment processing, this is not a benefit as it's the only option, i.e. does not win on the merits. As for game consoles, they're not essential. Smartphones are.
