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.
(See https://www.youtube.com/watch?v=CzQLRPwZjIo for usage example).
Seeing that Apple is the most valuable company in the world and they have a long history of abandoning legacy software (Apple //e, 68K, PPC, and soon 32 bit x86) and moving customers with them, that statement doesn't jibe with the reality on the ground.
What are the chances that people won't upgrade their iOS devices because they want to run an abandoned 32 bit app?
But iOS being such a locked down and closed platform means there is currently no way to preserve legacy apps or the data stored within installations. This is why dropping 32bit legacy app support is such a big deal.
I have some 32 bit apps that already don't work with newer versions of iOS.
