I think the rot began with the N.Y Bethel purge beginning with Ray Franz and Ed Dunlap et al.
After that, from the early eighties on, any scripturally sensible and liberating attitudes and practices were expunged, gradually the control got tighter and tighter, until any real Esprit de Corps was eradicated.
The cries of "Obey (worship) the G.B " grew ever more shrill , the desertification of their already dry Theology continued apace.
It is now certainly the worst large, High Control/Mind Control "religion".
To stay in it requires you to be a spiritual masochist.
