Not sure how much of this is ****. The US government already uses a lot of OSS because of the fact that many times it can be better than closed source alternatives and is also either cheaper or free.
Also, if the government used just closed source software, that would be a bad idea. OSS tends to get bug fixed and security holes plugged faster than closed source alternatives. Just imagine if a government just used macintoshes with macosx. Given apple's record for being slow on the up take for fixing problems in it's software, that'd be a bad idea.
Or imagine if a government relied upon microsoft's bitlocker (****locker) hard drive encryption (the one with the back door built in that gives police access to your encrypted stuff, which also equals eventually hackers being able to use the back door).
Not all closed source software is bad. If this is true information what nemesis posted, then it's extremely anticompetitive and would be hypocritical most likely. OSS tends to be linked with socialist ideals? I guess in the article it does, stupid trash; in an article you can view and link anything you like together for stirring up attention and feelings.
