Scan Man is being facetious (I hope). The reason for Microsoft making this decision is two-fold. First, they put egg all over the EU's face, and second, they (potentially) avoid having to bundle competitors' browsers with their operating system. Do not confuse this as being something the EU decided should be done.
I'm unsure whether or not they expected the EU to take that lying down, but I can't imagine they'll go for it.
