We have a saying at WikiTree: Privacy controls are for privacy, not control. Privacy Levels and Trusted Lists enable you to collaborate while preserving necessary family privacy. They're not intended to enable certain family members to own and control the family history ...
... the Profile Manager should not think of themselves as the owner of a profile. They're more like a steward or curator. They lead the family collaboration. They have a responsibility to share the profile with other family members. If they don't want this responsibility, they should let another family member be the Profile Manager.
Please remember the Honor Code says:
I. We collaborate. When we share ancestors we work together on the same ancestor profiles.
III. We know mistakes are inevitable. We don't want to be afraid to make them. We assume that mistakes are unintentional when others make them and ask for the same understanding.
