The genealogists are always happy to share their data. It's part of the culture.

There's no open source genealogy programmers because the young nerds that do open source dont care about genealogy.

There are others. I guess there aren't many, but there are some.

I care about genealogy! Of course, it's debatable if I'm considered "young" since I'm 30. I think maybe there would be privacy issues and personality rights to photographs that would get in the way of such a big family tree.

Not to mention a security issue as well since most financial institutions ask for your mother's maiden name as a security question.
