I'm afraid this is a sometimes sad reality of technology. I have a $700 iPad that is not supported by iOS beyond 10.3.3 and as a result some apps will not update; some apps will not install; and some apps just stop working. I'm not happy about it. Of course, this is not unique to Apple products, although it seems worse, since some we tend to become dependent on. I have a box with two old iPhones, a Windows phone, a Roku original, and two Fitbit watches. All 100% mechanically and electronically functional but no longer usable for their intended purpose due to software obsolescence. If I lose a couple more iPad apps due to iOS changes that I can't get, that device may to into the box, too.
I also have a box of expansion cards for PCs--faxmodems, display adapters, a firewire card, USB expansion. All work but my current computers don't have the type of expansion slots they use. A fully functional Dell computer, I just took to the county recycling center. I works totally, but not up to current speeds and limited to 16GB of RAM.
OTOH, my 2000 Subaru still runs fine with 225,000 miles. Radio, CD changer, Air Conditioner all still work. No modern electronic devices at all. My fancy EGO lawnmower, though, had to have a replacement of its $275 battery after only three years. So, to the O.P., I agree with and appreciate you position. I hope the new tax laws leave us both with enough money to replace our obsolete electronics.
