The rest of my post to you addressed exactly your concerns as to whether it would be worth it.
Apple's response to the proposal was that there was no need for a security czar to oversee the actual response of coders to fix security issues.
But I also covered the fact that it doesn't matter how much accurate information Apple puts out regarding a FUD attack by the media. The media knows that FUD sells better than accurate, but unremarkable stories.
And then there is the fact that some in the media will have an agenda.
I also drew attention to the similar situation the White House has with the media and FUD. Lots of FUD, and the media ignores the accurate and factual information that would dispel the FUD. Agenda coupled with laziness. Easier to print FUD that sells than go out and get accurate facts that don't sell.
So yeah... Apple doesn't want a security czar, and it wouldn't change anything about how the media responds to FUD.
Sucks, but true.
