The Qt Contributor's Summit just wrapped up today, and some of the discussions [0] touched on the author's points [1][2].
Unrelated to above, I just wanted to make a note: Just because the standard is out does not necessarily make the language easier to use; it is entirely compiler dependent. Also C++14 was not supposed to be as big of changes as C++11, if I recall correctly every-other standard is supposed to be major-minor changes to the language, though I don't have a citeable source on hand for that.
