Taking a step back for a moment. I believe it's possible to visualize just what is at stake for large closed source companies that have been "printing money" for some time now. The party has been raging for a while. They can see the sun rising on a new dawn out the window and know it has to end some time. Not sure if open source is a threat to Microsoft? Read: Open Source: Severe competitive pressure on Microsoft as it presents quotes from Microsoft's 10-K SEC filings. (SEC filings are a little more stringent than marketing spin of course).
For this reason, marketing from companies like Microsoft is grasping at straws to spread FUD about open source and keep the party going. It is unfortunate to see this is successful in the short term as illustrated by an article by Patrick Thibodeau at Computerworld. There is a perception apparently that open source is anti capitalist. The truth is precisely the opposite.
Educating to counteract this kind of marketing FUD is one of the reasons FOSSLC exists.
I particularly like Scott McNealy's take on open source vs. closed source below.
