I think some do indeed live under a rock. Plus the org. of course would never say anything negative about our numbers* (and why should they). It is only those who are in positions where they have to know i.e. elders connected to Bethel branches. One elder and his wife told me a few years or so ago that hundreds are leaving the truth. This was before the pandemic. Now things must be even worse as the pandemic made "fading" easier. Personally I do not know anyone in our congregation who has faded like this but I do have reports from friends. Actually that is a lie, I do know of one who is POMO now. I wish I could have a heart to heart with him, but I am supposed to not know why he left, and I am not that close with his wife. I only found out from his MIL that he had been talking with apostates....
The elder and his wife I mentioned above did make a point of saying that the online presence of opposers is playing a big role in one's leaving....
Over all, our congregation is pretty solid, as far as I know. But all it takes is some disappointment in the org. or misunderstanding and then reading stuff on line ...
*I don't know how others mid week part on the annual service report went but ours talked about growth on some obscure islands and two born in young people getting baptized. Then we had 4 experiences which were more about how to take the opportunity to talk to people informally. But there were no results, at least not yet. (But that's OK because whatever we say may stick and re surface during the GT).
As for the actuall annual report numbers, has anyone really looked at them and compared them with last year? I haven't. Maybe JWI?
