Please read the specification.

Sending "DNT: 1" does not, in any way, improve privacy.
It's sole purpose and action is to indicate a user preference.
It is not a light switch.  It does not turn anything on or off.
What it does is tell the server something useful: that this user
has chosen the following preference.  That's all.

The default of whether tracking is enabled or not given the
absence of a user's expressed preference is determined by
things entirely outside the scope of the WG: regional laws,
out-of-band consent mechanisms, user account settings, the
full moon, and other things that we are not concerned with.
