By using technological means the process of protecting the whistleblower is doable, and many doors of communications are possible.
However, the process does not end there. If either side of the process has their primary goal of revenge, then there is no party on the moral high ground.
The reconciliation process does require communications between both parties. If all parties can openly communicate, then full reconciliation is a real possibility.
Perhaps only one party is willing to reconcile the relationship with the whistleblower. If so, technology could also be a method to facilitate that.
Maybe providing parties a way to anonymously communicate with each other, perhaps without identifying either party, so some dialog could take place is a worthy pursuit. It may be that one party in a collective would like to reconcile, but is unwilling to be identified to the collective. Allowing private dialog to bring some form of reconciliation, perhaps without ever letting anyone else know, is better than remaining adversaries forever.
Is there interest in this?
