"Pushing the open source concept too far into areas where it's not applicable will lead to universities and taxpayers shouldering the cost of software development for business, and doing it less capably than specialist software development firms." A rebuttal was published by Leon Brooks on 6 Apr 04 (How independent is independent?). IPI's reaction follows.
