Without all the info on WT''s activities and business plans all we can do is take a stab based on what's public and/or can be observed.
Mass exodus as in the majority of the congregation upping and walking in one fell swoop I doubt it. A slow dribble is more likely but a tipping point will be reached eventually if they did absolutely nothing. They are in the process of changing to a religion of movie producers and JWTV so I'll see where that goes before I cry "ding dong the bitch is dead."
But, where are you up to on this thread, from what I see SBF is now actually providing a community service of fact assembly and deployment - I'm impressed, very creative way of announcing your opinion on available selected facts.
I really feel that what you see is definitely not all there is with WTBTS so I'll continue to watch this space.
