Mac users do bitch about the OS, there's forums where they have done so for decades. There's still folks calling for Apple to fix the fucking Finder. I used Mac OS back in the day and was one of the early users of OS X. But none of this was magically intuitive, people did and still bought how-to books and spend hours Googling tips.

And yes, Windows hasn't been that great over the years, but like most tools is manageable with effort. Windows 8.x has been a step backwards on the desktop but Windows Phone is surprising good.

As a pro I still think GUIs are one piece of the system, but CLIs still rule in my world.
