I had not thought of this aspect of what they're doing before. However, for a couple of years I've thought they were not very interested in new recruits. Sure, they're still doing field service of some sort; but the material they are presenting does not appear to be serious about attracting new members. I've been reviewing available assembly programs and most of that is aimed at internal issues, not the public. In fact most of it would send anybody with the brains God gave gravel running away screaming.
As noted above, the real wealth of the WTBS resides in its real estate. If they can push out a bunch of the "weaker" R&F concentrate the hard core in fewer Halls and sell the rest, the stand to make a pile of money.
