$200MM is a lot of money. It seems rather unsavory and uncool that Google bailed out Levchin and their investors.
You seem to be attaching a lot of motivation behind the acquisition that I haven't seen elsewhere.
But why would Google have any interest in "bailing" them out? Regardless of whether you think they were worth the money, I think it's a stretch to call it a bail out as if Google was using its corporate money to pay friends off. I suspect Google just saw a good team with some decent projects and interesting ideas, and used it to add to their social expertise.
