I get your point, but the question remains; what are they achieving other than perpetuating the frenzied media cycle? It's their free decision, and if I had a horse in the race it would be theirs, but IMO they'd be better off revealing less and maybe skipping the interview altogether. But their calculus informs them differently, and clearly see the interview as connected to their future business endeavors and/or a public forum to settle a score or two. I can't help but think it might backfire on them.
