I hope this doesn't sound harsh, but this may be an example of shunning working as a benefit; they will be left alone to figure things out without constant pleading to return. I know it made it easier for me. If my family had been begging and pleading with me to return, it would have been more difficult to make my way out. Shunning is a terrible practice, so unloving, yet I believe it backfires for the borg in that it gives time to think. I hope they never go back but make very successful lives for themselves!
