i do not believe they are bad guys.

because it's free PR for them and won't affect their revenues at all.  most
end users really don't care, and some end users really do like web error
redirection.  opendns could not succeed if everybody hated this stuff.  but
even though google doesn't do it and google has a more-recognizable IP addr
for its resolvers, opendns continues to thrive.  there's no pent up wave of
consumer hate for "web error redirection".  i thought there would be.  now
i just want there to be a standardzed in-band opt out mechanism.  i expect
that comcast and opendns, at least, will honour it.  various coffee shops
will not.  but if properly expressed, this signalling could enable google to
offer this as a service for those whose packets do explicitly request it.
(that is, google's default will probably remain "no", but if DMNF is present
and NWED=0 then they might treat this as an honest revenue opportunity.)
