People are scared to confess for the same reason they are scared to leave...
a person could lose their entire family and social structure.
So when an article like this comes along it heightens the feelings of guilt over trivial (and sometimes more weighty) wrongdoings.
Then what happens?
To relieve the torturous guilt feelings the individual does more.
More donating of time and money.
More self flagellation about trying to walk the straight and narrow.
Also, the individual "gives up stuff" maybe its watching sports.
Maybe its watching TV in general. Maybe its social time...
whatever it is the poor person makes up some kind of penance and tries to carry it out.
This all can only benefit the Org. Their lazy words in the article are meant to be a guilt trip punch to the gut, like cracking a whip on the poor publisher who hasnt managed to be a "perfect" Witness yet.
