I still think the authorities should have taken the offer of the men to be taken and prosecuted, possibly with no permanent contact and or monitoring, visitation only, whatever.
Let the sect die out.
Let the children stay with the collective mothers. Collective mothering is still happening all over the world and only became rare in the modern world decades ago.
The government has entered and disrupted a primitive society. A world where the children have learned to function. Removing them and placing them into another world will result in trauma and non-functional failure.
Educate them on site and make them aware of the abuses in the sect.
And let them step into the modern world of multiple divorces, multiple stepmothers and fathers, multiple stepbrothers and sisters, multiple and temporary cohabitations of parents with children, weekend visitation, drugs, violence, abuse, etc.
Keep the kids out of foster care. Foster care system is a disaster. A huge supply of children are to be had by a large number of physical, emotional, sexual abusers and predators. Not to blame those that truly care about their foster kids.
A 1986 survey conducted by the National Foster Care Education Project found that foster children were 10 times more likely to be abused than children among the general population. A follow-up study in 1990 by the same group produced similar results.[17]
The American Civil Liberties Union's Children's Rights Project similarly estimates that a child in the care of the state is ten times more likely to be abused than one in the care of his parents.[18]

Her investigation shows that 60% of children in the Texas foster care system are being drugged with powerful psychotropic drugs that have not been approved for children. Yet, "Children as young as 3 are receiving powerful, mind-altering drugs."
