It has been known for some time that Microsoft doesn't care about it's user base, using any excuse to force them into buying newer systems that really aren't needed to run Windows at all apart from the built-in list of incompatibilities.
At this point sticking to Windows 10 and bullet-proofing the system, or moving to a good Linux distribution would be the best option, rather than giving in to their ever increasing demands and abanoning your old hardware for a newer and shittier Windows 11 setup.
