No, they're not. As other posters have pointed out the organization had a 'brand' of religion throughout the 20th century thst 'sold' pretty well, 8 million members is nothing to scoff at. But that brand has become stale: they now rely on the children of existing members to keep existing as an organization, and yet they offer nothing to kids or teenagers, for instance, in the way of youth groups that would keep them interested and connected and coming back. They also ask 'young ones' (their very term for non-adults sounds like they still think they're in the 1950s) to make all kinds of sacrifices at school as far as a social life and sexuality go. So about 2/3rds of children leave by adulthood, and really, who can blame them even just on non-religious grounds?
Does the Governing Body do anything about that? Not really, they put out 2 minute Caleb and Sophia cartoons that are either creepy (Sparlock, dying for not paying attention at meetings), set kids up for embarrassment and isolation (telling classmates that their mothers (pl.) won't get into paradise, like that's gonna go over well), or the same old message kids hear at the hall every week (preach, dress up, obey the Governing Body, give the Governing Body your ice cream money).
The Governing Body is going down with their own ship.
