      The San Bernardino killers were already dead. Does that eliminate the public's interest in knowing whether the FBI secretly coerced Apple?

      Absolutely not, but that's a different threat model from 'spoofing the actual user'.

      That was just one example. The user whose desktop PC is on an APT-pwned network is another CT failure case that fits the usual threat model.

      The user never learns that his PC is seeing a fake private CT view because the upstream link simply blocks his device's attempts to gossip.

      OK, but one answer to that would be multiple devices/networks, which most of us have.

      By "most of us" do you mean rich people in developed countries who can afford multiple personal devices? ;)

      But even users with multiple devices are vulnerable. If the attacker pwns my desktop PC and it can't gossip with my laptop, I'm still pwned.

      No, if my PC nwk is pwned but my other session isn't, I should see different results.

      Your devices will but you the user won't, unless your desktop PC can gossip with your mobile, which it can't because its network is pwned.

      Unless you the user is an ubergeek who's in the habit of manually cross-checking CT log head bashes every few minutes...

          Me too? But good luck with new Twiitter UI - I have no idea what thread or how to take you off.
