Thank you for this comment, this explains quite well something I have not been able to put clearly myself. Whatever organization a firm decides to follow, it needs 'something' to coordinate efforts within itself. Hierarchy is one way, having very clear focus (and a culture shared by all) another one. That's also one of the reason most big and successful open source projects manage to get away with much less explicit organisation.
