Actually DNT is a voluntary agreement, that advertisers only agreed to in principle on the basis that DNT was opt in and not opt out. Thus advertisers will ignore IE 10 DNT because it is an opt out, and not opt in.
Thus Microsoft isn’t really helping anyone. They are scoring cheap PR points that only naive people believing Microsoft has their interest at heart, which they don’t. Microsoft flopped in the advertising business just recently writing off a staggering 6.3 billion dollars from a 2007 ad company acquisition.
So Microsoft’s attitude is if they can’t make it in advertising, they will spoil it for everyone else which includes their rival Google.
