This is excellent summary, thank you Tim. We should not forget that
the metadata are interesting too (and thus we also need dns privacy,
we don't have right now).

Also one of the reasons to encrypt everywhere is that it makes much
harder to decrypt everything. The more encrypted "noise" we have in
the background the better.

P.S.: And I am not known for my love for CAs :)...
