I wouldn't be so assertive about that. No OS is perfect, and as we see here, windows is no exception. It's mostly a matter of being used to living with those imperfections. At least on Linux, nobody is making those worse for you for "fun" (actually for their own profit at the detriment of yours), and many more nontechnical users sense that just fine (just the way copilot was forced is baffling).

> There are still plenty of Apple ecosystem-specific integration points and features that are still not available on Linux, like Apple Notes/iMessage/AirDrop/AirPlay/Handoff between macOS and iOS

KDE Connect solved that, and much more, many many years ago. I don't know the situation in the Apple walled garden, only that any hurdle there is the result of Apple abusive, user-hostile and anticompetitive practices that should (and will eventually) be illegal outside of the US.
