Agreed, and it's really been disgusting me lately with MS. Not just IE, but virtually every MS product or service is 99% marketing-driven, to the point that it should be making politicians jealous. They don't try and prove why they're better, they just tell you that they're better. And no, cherry-picked results don't count.
All they do now is try to force a narrative about how they're "better" than some competitor in some wholly subjective (or at least, objective-yet-inadequate) way. Google vs. Bing? That entire fiasco was downright embarrassing.
