It's sad but predictable to see your comment downvoted for offering an interesting perspective. Especially considering most responses are sarcastic "yeah Facebook is small", ignoring your explanation. I'd have thought most here acknowledge your point that you can't arbitrarily add people/cash to a team.

In general I don't like exclusivity, but I don't downvote for a well-intended, thoughtful contribution. I do think you ignore the more obvious motivation of them wanting a larger cut of the price.
