Earlier quoted context omitted.
They could offer 32bit app support as an optional download, just like how 32bit Windows 10 still offers the 16bit NTVDM and MS-DOS support as an optional install on demand. Really sucks to lose 32bit support for legacy apps that used to work, especially when it might be a companion app for hardware/equipment that cost much more than the iPhone X (like your car).
Do you realize how many security vulnerabilities have been found in Windows caused by supporting legacy apps? I have some 32 bit apps that already don't work with newer versions of iOS.
Apple is a hardware company, and its need reason to push it. But what I do with hardware is run applications, and the applications matter more to me than the shiny (or not) box they run on, insofar as the box has the hardware to provide the UX that makes the software usable.
I am not talking in abstract; when Everyday Looper goes, iOS will lose about half its value to me.
