That simply isn't true. DNT sent from MSIE 10.0 has no meaning.
It is equivalent to not sending DNT, as far as "tracking business"
is concerned, whatever we might mean by tracking.

Only in certain jurisdictions.

That's certainly an option.

No, the user agent sent a request.  The site will respond as requested
and do whatever applicable regional laws allow with the data collected.

They don't claim that IE10 isn't compliant---rather they presume the validity of the signal---they just say "here are your choices."  Of course, this may not be compliant with European law, but I believe the group had decided that sites could degrade users' experiences who don't grant exceptions.

Removing the DNT signal does not, in any way, impact compliance
with EU laws.

I'll be happy to make removal of the DNT field transparent to the
UA if there is a mechanism to do so.  The UA can choose how to
communicate that to the user.
