There's at least a few factors:
- like boiling frogs, where things worsen gradually and you don't notice / hurt enough until it's too late
- accumulated bandaids over time to keep it bearable. e.g. knowing what settings to disable, perhaps having powershell scripts to debloat new machines, etc
- inertia. Hard to make big changes in general, even if they would help, because change is hard and usually costly
- forced to use Windows at work
