This is the kind of douche you don't want to do business with: McGraw Hill CEO discloses Apple Trade Secret on national TV

Forget scammers in Nigeria, it's people like this that will ruin your day. Like Gordon Ramsay going mental on some muppet, I don't find it surprising that Steve Jobs flips his lid when idiots pull this kind of crap. I don't think he'll blacklist McGraw Hill from the event like he did with ATI back in the day though.

Some people speculate "controlled leak" - not a chance. A controlled leak doesn't come from some nerd CEO the day before a major press event.
