I am now convinced that Computerworld may not even understand the product Linux, which gets so much FUD publicity via your articles.
The article I'm referring to "Code submissions to Linux are public!" is available at http://www.computerworld.com.au/index.php?id=1224882570&fp=16&fpid=0
And only very stupid people would put an off-the-shelf operating system into a highly secure environment. At least with Linux you can audit the code - because it's publicly available - for free!
Some objectivity please (or hire someone that knows Linux).
