I think it is the ubiquity of mobile devices that is particularly working against Apple here. That's a difference that could be a reason the consoles might potentially fly under the radar even if they were forcing users to buy exclusively through their stores and having locked down purchases. However Apple forcing the hand of legislators may end up having consequences for all those platforms.I could agree with that. But then again how does Sony, Nintendo etc handle in-app purchases?
In the end it is none of Apple's business what applications people install on hardware they bought. The security claim is somewhat true, but it is not their business if an owner chooses to take that risk. They could easily implement exactly what they have on MacOS, which is that by default the system only allows signed applications and users have to explicitly turn it off. If Apple doesn't like not having control over what gets installed, then they're free to exit the mobile device business. No-one is forcing them to make these products and the huge profits that go with them.
