This sort of transparency is fundamental to open source. The twentieth-century view of business sees control as power, and that drives secrecy. But in the connected society emerging in this century, control points are damage in the mesh, something to be worked around.

Far from diminishing Apache, this act of radical transparency elevates them and empowers them. Repeated time after time at every level, this sort of transparency has fostered growth and made Apache one of the most succesful open source communities to date.
Transparency fosters influence while control diminishes it - a hard lesson for modern business, but a crucial one.
