"Thus forcing unknown millions of people worldwide to upgrade an ENTIRE CPU and Motherboard just for the next version of Windows"

I don't know why you must come conclusion at this point, no one force you to upgrade into next version

as far as I know, when you buy windows 10 license, you tied into certain edition that would work for that edition. nothing mention next OS (in this case windows11) should backward compatible with last edition

if you think 7-8 years is bad, think how much smartphone that not receive update for years, most often that this phone didn't receive update at all

and google and apple literally making new edition of android/ios that break depedency every year
