I don't think it's crazy IF Geni.com choose to support both private family trees and a public "world" tree. That's o.k., in my opinion.
What *IS* a problem is when there are private profiles connected to the "world" tree which are ancestors of public profiles.
There needs to be two capabilities and understandings:
1) If I choose to connect to the "world tree", then I am agreeing that all older (however Geni decides to define that!) profiles connected to that "world tree" will be public. I can choose to make other profiles I manage also public, but "older" ancestors (as Geni defines) will always be public. {It would also, however, be nice to have managers have some curator-type privileges to "lock" authenicated information.}
2) If I choose to take profiles I manage that are currently connected to the "world tree" as private, then I can do so -- with this caveat: public profiles already co-managed as part of the "world tree" and not subject to privacy laws will remain public; I will get a private copy of them so that I can manage the completeness of my private tree without being affected by whatever happens to the "world tree". {The intent would be to deal with the existing history of bad and unintended connections.)
Those provisions, it seems to me, would allow Geni.com to support both private tree-builders who like the features of Geni.com for putting "their" tree on-line -- and -- to provide for the building of a "world tree".
