3P app developers are also complicit. Often they deliberately cut off support for old OS's and old devices, because it's "too hard" to support them or whatever. Everyone seems to be working together to keep us on the hamster wheel.
Granted, it is hard. It's a whole extra version to QA on. If it works fine, fine, but if there are consistent negative user reviews on a version with < 5% market share, it's not worth it.
We don't support old iOS versions at all. We can't source new devices on old iOS versions so we can't reliably develop or test on them.
