I think "trust CEOs" is significantly less supported by Edelman's data than "reduce press freedom, emulate China," but I'm just a random internet commentator, not a high quality journalist like Felix Salmon.
I'd also note that the 3% drop also appears to be barely outside the survey's margin of error (survey population size: n=1,150).
