I think someone must have heard/reported the radio transmissions during the flight because during the live commentary of the race Brian Spreckley commented that there would be penalties assessed after the finish that could change the race outcome. Since he wouldn't have had the flight logs at that point to determine start or airspace penalties, it's a pretty good bet that he already knew about the radio chatter.
