That's been the argument since Windows XP and to a lesser extend Windows 98SE were released. Too much has been added! From my experience the thing I dislike about Windows 10 is how often I find myself using WidnowsKey+X to use it.
I've been around a bit longer. I remember that pretty much every "major windows version" (including the first) drew ire from Microsoft PC users. People complained about the transition from DOS to Windows (which was rough), from Windows 3.1 (and WFW) to 95, 98 to ME (probably one of the worst transitions), 98 to XP, XP to Vista (which had 90% of what everyone loved in 7), 7 to 8, and now 7 to 10.
Each iteration people hated it, then loved it. I don't think it's any kind of "Stockholm syndrome", each version introduced and refined new functionality that people grew to love. What a "Desktop OS" means seems to be really in a state of flux right now, so it remains to be seen if people love 10 (I'm enjoying it, but then again I liked Vista).
