I get what your saying but this is a very hard balancing act for Apple. I have an iMac from 2008 that is still working really well. I love what a fantastic machine they built, and for almost 10 years I could continue to upgrade the OS to get all the new features they developed. With the "High Sierra" update I found out my computer was too old to receive the new OS. This made me really upset at first, because there are a few apps I want that I can never have on that machine. But at some point if they continue to allow me to run the new OS it will result in an unusable device, like you are experiencing. But on either side of the fence you will have angry customers. Apple can protect customers from updates that won't work correctly on their devices, or it can deny them access to new apps and features they want on old devices. Either way the customers will be disappointed.
