If I recall, Enlightenment used to have a rather focal fan base at one time. The DE was a lot prettier than most of its contemporaries, and was relatively lightweight despite having animated effects and everything. I always thought EFL was one of the hidden gems of the Linux ecosystem that was left in GTKs and Qts shadow, but after reading the article (back when it was first published) I realized there was probably a good reason it never got popular. I thought the story was embellished, as thedailywtf articles typically are, with the "SPANK! SPANK! SPANK! Naughty programmer!" stuff, so I downloaded EFL source code and checked. OMG, it was a real error message. (Though I believe it has since been removed.)
The company in question using EFL was (probably) Samsung, who apparently still uses it as the native graphical toolkit for Tizen.
