True. But if strong authentication at Internet scale is so
hard that people fall back to cleartext then that's worse.

Strong authentication can also in some cases expose identifiers
where you wouldn't otherwise need to, which is not the best
thing from a privacy perspective.

So for at least some of what's recently reported, it seems
to me that there is value in exploring whether opportunistic
encryption is worthwhile, maybe for cases where we don't yet
have strong authentication schemes that are privacy
friendly and that are deployable at Internet scale.

But yes, we also need to worry about strong authentication
and making that easier/better. I'd be happy to see folks
working on this from both approaches - making strong
authentication easier/better but also taking the approach
of seeing whether and when opportunistic encryption adds
value. I would not be happy if we dive into either one while
ignoring the other.
