Re: action-231, issue-153 requirements on other software that sets DNT headers

I don't think the terminology is inappropriate. Within the context of
'expressing an individual's choice', an individual selection of DNT-1 is
expressive of that individual's preference for privacy, not of any
broader social impact on global privacy that may or may not result from
that choice.

This seems right to me.
