Sauer of the Department of Economics at Hebrew University of Jerusalem, and president of the Jerusalem Institute for Market Studies. has written a article saying that the hidden costs of OS add up to a higher TCO. However, The greater danger Sauer writes, is that of a OS project forking. "The forking of open-source projects occurs when passionate disputes between open-source software developers over product design lead to the splintering of projects into a multitude of varieties. With proprietary software, forking generally does not take place since development is centralized within a firm and disciplined by market forces."" I've always seen Forking as something of a blessing... it's the abandoned projects are the ones that are in danger.
