Not really all that secretive. I've known about the logistics for years and that one of the main reasons was to drive fans to join their official clubs so that they can get a bigger cut of the profits, taking Ticketmaster out of the equation. It's a smart business move, but it comes at a price....literally. You have the ones joining the fan clubs actually paying more of the tickets because the band, manager, whoever can now charge whatever they desire. And you have the fan that doesn't join actually getting shut out.
