I agree with about 50% of what he said.
My strongest objection to the article is that the various genie animations in OS X should fall into the condescending category. Windows and Dock icons constantly move around, and to have a window or icon zoom towards where it originated from once I close is helps me greatly to orient myself. Just picture the Mission Control view without the transition animations. You would have no idea where the windows go without them. However, since they exist, you know where windows are, even if they end up being fully covered once you exit it.
Regarding the new “talkative” UI from Microsoft… I think there’s a popular term called TLDR and that pretty much sums up the failure with their new philosophy, so he’s completely right about that one. Also, double failure: That UI is condescending… but at the same time expects people who don’t understand to read great lenghts of text? Haha, yeah right.
