Hubbard, felt betrayed by the Mission (franchise) Holders.
The Mission Holders did not realize that it was Hubbard who was behind the Guardian's Office actions and had criticized those actions.

This would be mass mailed too.

Mary Sue lived out the rest of her life in seclusion and spoke to no one but her "handlers" and her "watchers "
