An issue sidestepped by this article is whether the statement in the second paragraph is correct:

> ... tech and ad companies who say they comply with Do Not Track could simply ignore the flag set by IE 10 and track those who use that browser.

That doesn't quite work. Web servers don't know what browser is on the other end of a connection. Yes, they know the "User-Agent:" line, but that is not the same thing.

Claiming to follow a privacy standard, but then ignoring it based on a conclusion reached via fallible means, is a bit scary. It strikes me as the beginning of a slippery slope, regardless of what position Microsoft ultimately takes with IE 10.
