The reason why the rudder is at the back rather than the front of a ship is the same as why a pendulum rests straight down, but a pencil won't balance straight up - stability. I can't really see any links between that situation and the one being described in the article.
Not to say there aren't some good points being made - I think though the analogy being used distracts from, rather than adds to, these points.
And yes, the lack of capitalization does make it harder to read.
