This was shamelessly stolen from Slashdot: It was recently reported in eWeek that "A senior Microsoft Corp. executive told a federal court last week that sharing information with competitors could damage national security and even threaten the U.S. war effort in Afghanistan. He later acknowledged that some Microsoft code was so flawed it could not be safely disclosed." (Emphasis added.) The follow up from Microsoft is even better: As a result of the flaws, Microsoft has asked the court to allow a "national security" carve-out from the requirement that any code or API's be made public. Microsoft has therefore taken the position that their code is so bad that it must kept secret to keep people from being killed by it. Windows - the Pinto of the 21st century.
