Same story, different year
These are the same complaints made when Windows Me came out requiring 3D acceleration, or when Mac left Motorola for Intel, and again when they went to ARM.
People treat a PC like an appliance they can keep on the kitchen counter until it quits, not a complex mix of hardware and software that eventually is surpassed and can no longer be used safely.
A lot of the improvements made to Win11 are security changes that are baked in, rather than simply tacked onto Win10. Which makes it much easier to "untack". This is very noticeable with regard to MS tightening driver compatibility to eliminate those that pose security risks, like old Logitech camera drivers. People complain their "perfectly functional" cameras no longer work but don't care that the old drivers left them vulnerable to side-channel memory attacks.
Eventually your jalopy can't keep up with traffic on the highway and becomes a hazard to everyone else on the road. And all those pre-Win10 machines are those jalopies.
