> If the developer does not have any interest in updating their own app, do I as a user care about their apps?
A developer's primary interest in their app is to earn an income. A user's interest is in using the app for whatever functionality it provided. There's no symmetry here.
If the developer doesn’t want to update their apps to fully support my device, then I would look for an alternative.
There are almost 0 cases where I would withhold an OS update in order to keep using an specific app, let alone change my device, and I’m completely on Apple’s side for finally killing 32-bit.
