I think a big part of why Oracle have been so vocal about the details is because of the wave of bullshit launched from Auckland about Herbies etc.. It would be pretty grating to come back from so far behind and then have half the public believing the crap and thinking you did it by cheating.
That's probably part of it but they were also very open about being measured every day and even grumpy stated immediately following the event he felt OR won fair and square. The NZ media had a different attitude. In general OR has been much more open than ET - big base tours for lots of people for the past year, press tours during ruddergate, etc.
In contrast we hear about a clean video of the base in NZ that never materializes.
Have to presume that Clean got the ride on the boat from RNZYS in return for his silence about the team, and beating up Oracle at every chance he could, unless of course it involved sucking Jimmy's dick after he won.
