It's that simple

You seem to be missing the point. All software has a point where it reaches end of support. The problem is Windows 11 has significantly increased the system requirements so that only computers produced in the last 7 years or so are "compatible" and lots of perfectly workable but slightly older machines are now destined for the ewaste burn pit purely because of that decision

Yeah, but the system requirements for Windows 11 are a good way above those for 10. Many people would need new machines; whereas Linux still runs decently on hardware from 2003.
