Why not? It's fine. (And easier to follow in mail I believe.)

I suspect this is one where we're better to recognise that
nobody's fav term is correct;-) It's entirely legit to consider
how security/privacy analyses affect the market, and how they
affect society, and how they affect specific communities, and how
they affect the set of people who use or care about the Internet.
Those are all valid, as would be other sets of interested parties,
and I suspect we'd never reach consensus as to the relative
importance of each. I think if we each accept that other folks
rate those differently for reasons that are possibly as valid as
our own, that might be good enough.

The elephant metaphor isn't my favourite. Even if we're each
scrambling around in the dark, there might not be exactly one
elephant. In this case, I think there definitely is more than
one. For example, we have the enterprise n/w vs big-I security
differences, and we also have the commercial/govt surveillance
vs. human rights/freedom differences. It may be my lack of
imagination but I can't see how those are part of one elephant.
(And I think that's true regardless of one's opinions as to any
of the locally-perceived potential elephant parts:-)

Cheers,
S.
