I'm not sure how that is in any way relevant, but regardless you know very well that it is completely disingenuous to suggest that someone just "build a new app" for another platform.
Not every spreadsheet is the same. Not every chat app is the same. Someone isn't just going to go out and build another Fortnight because you can't get Fornight on the iPhone anymore.
It is not disingenuous, Iphone legitimately offers no major feature you can't get from Android.
You're arguing that feature parity is required for subsitutition, and that is an addled argument. It's not even temporally consistent, as you have prior versions of applications with features removed.
You can carry a laptop in your pocket. Sony VAIO had a mini edition around 2007. You can also use a bag, which has big pockets, and you can connect to networks and even cell networks.
Point is -- your argument here is very weak that the two platforms aren't substitutable, and there really is nothing left to say. Have a pleasant evening or morning, as the case may be.
