I'm POMO and I'm very happy to have open communication with two PIMO's in my older congregation. We can discuss everything and accept and respect each others position. They understand why I left but they are not in such a position because of their family. No pressure on both sides which is a good thing.
i believe the increasing PIMO's are pretty much the "hidden" scourge for the Borganisation. They can focus on apostates but it are the many PIMO's that (not openly) don't give a f#%k about meetings and field circus and keep activities as low as possible. Many also vote with their wallet. The Borg simply can't afford to lose all these "spiritually weak" (hahaha) members because WT loooooves numbers, even if they are manipulating them behind the screens to keep up appearances. Kingdom Hauls are already half empty, it's already a disaster. Yes, the future looks dark and it's all a matter of damage control for the eight midgets now.
How many? No one knows but they ARE increasing, just like the symbol partakers at the memorial, lol.
I hope the PIMO's will see a wondrous expansion in these exciting times.
