I wouldn't mind Windows if it were easy to rein it in, if I had granular control over what updates get applied and what gets trashed, and the ability to opt-out of updates. I wouldn't mind macOS if I could more easily control the UI bloat, preinstalled apps, and hundreds of background daemons/processes that are running that I never asked for.
I want to take my Operating Systems back to 2009 and have a version of Windows 7 and OSX Snow Leopard that runs on my modern computers and have all 3rd party apps work on those operating systems.
Or, just install Linux.
(no instead of now)
