It's obvious that Microsoft doesn't have as much to lose with a DNT default setting in IE10 when their profit center is tied to Windows and business software. They have MSN.com and Bing but both are money losers and at this point, hurting Google and Yahoo might be a better strategy even if it means "cutting off your nose to smite your face". They also hope that this will stem the defects from IE and help sell more Windows 8 upgrades and Surface tablets in general.

In regards to how people feel about tracking, people are always asked in isolation about tracking and of course everyone say's they hate it and they don't want to be tracked. The better question is asking them if they will accept the alternative. Scared of Facebook? Put a $5 fee per month to replace lost ad revenues and users will depart en masse. The reality is a big chunk of the internet and the services people rely on, love, and use daily are ad supported and if given the alternative of a free ad supported model vs. a paid model, they would choose ad supported.
