They are already ticked off.
Last year, a couple of these Black Hatters in a video demonstrated a claimed Zero Day infiltration of an Apple MacBook Pro at the convention that gained user level access through a flaw in the MacBook's WIFI.
However, the demonstrated exploit turned out to be done by using non-Apple hardware (third party USB WIFI card) and software (third party WIFI drivers) that is NOT installed in a MacBook Pro. The demonstrated flaws were in the third party stuff that would not normally be used on a Mac because the functionality is already built in. . . but they touted it as a Mac vulnerability. It took months to clear that FUD party up and get them to admit it was NOT a flaw in OS X as shipped by Apple.
The vulnerability was much more common on Windows computers that DID use the third party stuff... but the demonstrators said they chose to use a MacBook Pro because "they wanted to stick a lit cigarette into the eyes of smug Mac users"—so they cheated to damage Apple's reputation.
For all the supposed smugness of Mac users, it seems to me that Mac detractors are the truly self-righteous.
