It is looking a little like the "finger in the dyke" overlapping generations doctrine is having some fallout. It has to take some time before the wake-up effect manifests itself. Judging by the intelligence and age (and service record) of some arriving at JWN (only representative of a higher number), the thinking ones (ie; inner circle) are having serious doubts.
The harsh effects of shunning and the risks of being "outed" suggests to me there are big numbers inside the Borg who are simply not fooled anymore and just hanging in there. The flow could quickly move from a trickle to a flood.
The "toes" bullshit was pretty desperate stuff . . . silly, purile stuff really. The GB are looking rudderless to me . . . but then where have they got left to go with "believable" doctrine . . . nowhere.
They don't need long-standing members, they just need door-to-door salespeople and money in the contribution boxes.
This is the bottom line . . . eventually they'll say to hell with keeping long serving people in . . . some fantastically appealing noo lite will eventually appear . . . to bolster the recruiting activity. A striking new doomsday prophecy is just around the corner . . . it's the only thing that works for them.
