So, how many people are employed by Auttomatic to work on this project?

One. Andy.

I’ve been poking around for some time and I’m a little surprised that not one person has been confused by the complete lack of security in BuddyPress.

You need to poke around a little more.

Also, privacy is on the BuddyPress roadmap.

As Andy states, implementing privacy in BP or any social network is not an easy task. I am working on updating my older privacy component to work with BP 1.2 and WP/WPMU 2.9.x. It will be awhile longer before I have a working alpha for testing. But, privacy is coming to BuddyPress!
