Apple's goal is obviously not security, nor is it to force things to work with the latest version. The purpose is to break backwards compatibility of the apps themselves. Make apps stop working on older versions of the OS. And the OS isn't supported on hardware more than a few years old. So your software you depend on breaks and requires an OS update and an OS update requires a hardware update and a hardware update costs $2,000 if you're lucky and 12,000-$20,000 if you have a lot of peripherals like color laser printers and scanners and audio converters that no longer have working drivers and the only option is to buy a new one of each.
