Some of that is also that what "native UI" means has shifted a bit. To look at Windows, Win95 had a thoroughly considered UI design that was very well adapted to both what it needed to do and the hard constraints on it. Win11 is... kind of a shitshow. (Are parts of it still from Windows 3.1? I haven't tried to track them down... but in Win10 there were a few dark corners.) It made sense to match the native UI in the Win95 days. It often doesn't now, it's simply not a target worth hitting. You could just use Win32 and target the older Win95 look, but apart from appearance issues, it was designed to work well in 1995, and we simply demand different things from our UIs now. Like support for touchscreens. Old Win32 apps are painful on touchscreens. (But, often, awesome without a mouse.) And those are real considerations, not oooh-shiny-new-thing designer BS.
