This sort of fear of change is oddly common in IT (you'd think tech folks would embrace the future).
With the Mac, I particularly saw it in the early days of OS X. For example,
this article on the Dock is… toxic, for lack of a better word. Some of Siracusa's rants about the Finder also came close. There's a fine line between "it's bad because I have some legitimate concerns" and "it's bad because it's different".
(I think some decisions with the Dock are a little weird. I think I would like the symmetry of having both the menu bar at the top and the Dock at the bottom fill the entire width of the screen, rather than the Dock having this weird, wasted space at its edges. But in practice, most of Tog's usability concerns seem… overblown at best and absurd at worst.)
