Consider that Windows 10 still runs on some 13 year old devices. macOS supports devices almost eight years old. That's MUCH longer than the average mobile support period. Desktop/laptop users can also switch to Linux after the support period ends to extend the life of their hardware further. If mobile vendors can't do that, then they should limit support to the expected life span of a the battery under average daily usage conditions, starting on the date that device sales are discontinued. That's certainly less than 13 years. Alternatively, the manufacturer could just unlock the boot loader after the official support period ends and provide the community with the resources they need to support the device. Some people will continue to use their device until it is no longer functional. Either they can't afford frequent upgrades, or they're trying to reduce electronic waste, or whatever. It's wrong to strand those users on an unsafe platform.
