Funny that they relate this text to this topic if they really target "apostate" stuff. Because they are calling people to check if it is true, whereas actually it is the last thing they expect them to do.
Of course "check for yourselves" often means "you don't need to check, we have done it for you".
About the disconnection between text and commentary, I remember in the French Bethel (in the 80's) the only rule was, ask a question and them make your 1 minute comment. But the question and subsequent answer could be completely disconnected from the initial text, and some made quite a game of playing dumb with it. For instance, a friend of mine once asked "What was Beth-Sarim?" and told the whole Rutherford story to a puzzled audience, while alluding to the present use of Bethel facilities. Don't ask me what text he managed to connect that to...
