I think the GB want them to direct people to JW.Borg because they don't want anyone discussing their beliefs the way we had to.
What would they do with the overlapping generations nonsense if they tried to explain when the paradise is coming? Or if someone raised the blood issue what would they answer now?
They can't let people waffle through teachings that are as clear as mud. They would quickly realise how stupid they are for one thing and no one would be converted.
