I'm not sure why you're counting the years of support for a version of the OS and not the years of support for a computer. The interesting thing is: if you bought a computer at year X, does it still receive updates at X+Y?
There's loads of relatively young computers which can't upgrade to Windows 11 and therefore aren't supported anymore. That's the problem, not how long Windows 10 was supported.
Apple did the same thing when they dropped x86 support.
