I was really surprised that they dropped the Book Study arrangement. It goes against normal cult philosphy for the leadership to give their members more freedom and more personal time.
It was either a knee jerk legal move to protect the organization somehow (why, I'm not sure) or the leadership was trying to stem the flow of people leaving.
Of course, no matter the reason, it has obviously backfired, as anyone who knows anything about human nature could have told you ahead of time. They underestimated the actual control they have on the flock. Over time the stress and load of work had been too much. Couple that with the failed prophecies and other various scandals and people were tiring of the fight and were giving up.
So they try a new tactic...give them an open night. Except, it's not really an open night. It was all a smoke screen. Tell them that they're easing their load, but them give them homework to do. What they should've seen coming was that if you gave a bunch of tired, stressed workers the freedom to not work, they're going to do just that...not work. They took advantage of that open night, not to do their homework assignments, but to enjoy the things that they had been missing previously, or catching up with things that needed to be done that they had been putting off for the sake of the WT.
They might as well give up on Family Night. It's a bust.
