While it is reasonable to assume a user's intent, it is also reasonable to assume a content publisher's intent to monetize their content. An advertising-funded web is the reality of today, unless Microsoft is proposing a radical change in this model.

The concept of Do Not Track, despite the emotional appeal of the name, essentially seems to be a compromise between privacy and advertising, keeping the advertising-based model intact while also allowing the extremely privacy focused (minority set of) individuals to have things their way.

Turning DNT on by default is a hardline approach and violates the spirit of this compromise. Instead, there needs to be more effort to constructively work with content providers, privacy advocates and advertisers to come up with a more explicit protocol that satisfies everyone's interests.
