I lost all interest in reading the article after looking at the msdn.com domain.
EDIT: Downvoters, I don't see how this is wrong. Microsoft has a long history of spreading FUD about competitors (Florian Mueller/FOSSPatents, http://www.scroogled.com/ [when their own practices are very much the same], sponsoring fake studies that show that the TCO of Linux is much greater than that of Windows, and so on.) I certainly would be interested in an unbiased opinion on the topic, but I don't think anyone on Microsoft's payroll can give me that.
