I consider the article a bit absurd. Emacs is only less popular relative to the set of editors one can pick today. Emacs has never been more popular or alive. melpa, emacsrocks, famous magit/org, even emacs confs and emacs talks at lisp confs..

Plus maybe "more is less" is adequate when it comes to emacs. Too many people may create friction or waste. Let it be low and slow, it's fine, emacs has stopped sprinting, it's in a nice hike.
