This is the next phase of their plan. They never wanted to be part of the Boy Scouts. They wanted to infiltrate the organization and, rather than assimilate, they wanted to displace the normal scouts, the male scouts, and so on. They wanted to consume the BSA and take it over until it was entirely a trash entity with just the name that would indicate any sort of connection to the original organization. Kind of when non-whites movie into a white neighborhood.
