They're half-right. Microsoft do keep supporting the OS APIs, but it's the UI frameworks that get half-assed and abandoned. Which is why so many people recommend Avalonia these days. Microsoft don't even reliably use their own frameworks - go through Win11 and see how many Windows Forms dialogs are still present in things like settings and Explorer. (WinUI is also a hybrid: since it uses the DirectX APIs rather than the old GDI model, most of it is in a userspace package that's delivered as an .appx)
