But I think the goal of the governing body is the recruitment of new members,
If that were their goal, than everything they did would further their goal.
But that is not what we see.
The org is very bad at recruiting (and keeping, for that matter) new members.
What the org is very good at is making sure that all JWs the world over follow orders perfectly (or as they would say 'remain united').
That is their goal. That is their main focus and all they really care about. They publish rule book after rule book so that every JW the world over knows how to behave in any conceivable situation. That is what the GB do.
Numbers may suffer, but lock-step conformity may not!
