It is a logistics issue. People replace perfectly working computers all the time. Sure, if you use Skylake you list performance from Spectre and Meltdown. You may not even be able to run Windows 11 on perfectly working x86-64 machines. But for poor people, power usage may even be more important than for you or me (businesses generally don't care). That Skylake's successors were so terrible is due to Intel and thankfully it allowed AMD and ARM-based SoCs to thrive.
