I've been tracking the evolution of Microsoft FUD for nearly 10 years now, and wrote a short history of the subject a few months back. But even I was impressed when I came across Microsoft's latest effort in this department: it's truly a masterpiece of its kind.
Whereas previous FUDs have revolved around details like the relative speed, price and legality of free software compared with Microsoft's own code, its most recent offering takes a different tack, and purports to look at the bigger picture.
It's a white paper from IDC, "sponsored" by Microsoft, on "The Economic Impact of Microsoft Windows Vista". But this is not some abstract ivory-tower analysis: on the contrary, it is highly targeted, and aimed at a very particular audience - the European Commission - that is proving to be annoyingly unaccommodating when it comes to letting Microsoft have its monopolistic way. Not content with slapping some juicy fines on the company for past misdemeanors, the European Commission is now starting to make unfriendly noises about the forthcoming Windows Vista.
