My core criticism is that the notion of "doing the real thing" is very poorly defined and can be easily misinterpreted. That makes this article potentially harmful advice to broadcast. Mind you, it might be good advice for specific people, where you know their circumstances very well and can clarify all the undefinedness, but it is too poorly defined to just send to unknown recipients who mentally fill in the blanks of the article in many, unknown ways.
