I presume this is an attempt at humor rather than just a snide comment, but as a humorless engineer I'll ignore that and respond sincerely. It's a well put together presentation based on adding graphics and text blurbs on top of screen shots. You can read through the whole thing using the right arrow key in well under 5 minutes, likely under 2.
I much preferred it to a video presentation, which even if viewed at 2x speed would have been much longer. And since it's based on showing screen shots, plain text isn't a good option. I have no particularly strong interest in dark patterns (and in fact have extreme distaste for them) but I found their mastery of the craft to be extraordinary, and the presentation to be well worth my time.
People (and organizations) have competence in different areas. I was genuinely impressed (in a dark patterns way) by the deftness with which they handle new signups: http://www.useronboard.com/how-ashleymadison-onboards-new-us...
