Microsoft deliberately violates the standard. They made a big deal about announcing that very fact. Microsoft are members of the Tracking Protection working group and are fully informed of these facts. They are fully capable of requesting a change to the standard, but have chosen not to do so. The decision to set DNT by default in IE10 has nothing to do with the user's privacy. Microsoft knows full well that the false signal will be ignored, and thus prevent their own users from having an effective option for DNT even if their user's want one. You can figure out why they want that. If you have a problem with it, choose a better browser.
素敵過ぎる
Apacheの変更で、設計上の欠陥があるDNT(トラックすんなよヘッダー)は、IE10の場合、無視されることになった。これは、クソな規格上、利用者の明示的なDNTの意思表示を求めているためで、デフォルトでDNTを有効にするIE10は、規格違反のブラウザーであるとのことだ。
コミットしたのは AdobeのRoy Fielding、DNTの規格考案者でもある。
