+1.
Emacs is a powerhouse of customizability, and it needs to work on functionality by default.

I don't think Emacs is held back by its authors. The article might not make it clear but RMS does not contribute much to the vision or code of Emacs today. Read emacs-devel, and though there's occasionally some conflicts, the authors are keen on progress aligned with what people expect from an editor.
Emacs is a complex platform, owing to its unique vision on blurring the line between user and developer. The authors do a great job of keeping that up-to-date.
