➢     Can you explain the comparison that I brought up regarding trusting the CA? That is related to " the client’s willingness to let their traffic be intercepted".
    
    
Subverting one CA cuts across a large scale of Internet traffic and might be noticed or can be routed around.  Certificate transparency helps prevent a single CA from being coerced into misissuance.  With this extension, someone doesn’t have to coerce a CA or force victims to trust a new CA.  Instead they have to gain the cooperation of the origin(s) they are interested in.  Further, if you mix in a coerced/force-trusted CA, you don’t even need the origin’s cooperation.
