I think the purpose of Cinquanta's communication was to alert people that some hard choices would have to be considered in the future due to financial considerations.
^ That's a good question. It would certainly be interesting if the ISU would open it's books to the public.
I actually doubt that NBC made a profit from the Olympics. They will say that they did, but such reports are self-serving and often padded.
I do not know whether the ISU gets any cash money from the IOC and its sponsors beyond reimbursement for expenses for the Olympics itself.
In the mid to late 1990s the bulk of ISU revenue came from US television contracts -- millions and millions of dollars annually for the rights to broadcast ISU events. Now that amount has dwindled to essentially zero. It is my impression that, yes, they pretty much do give away the broadcasting rights in the US for practically nothing (I don't know about other countries, such as Japan).
To me, all the signs point to a return to the model of the long past where the ISU is supported mainly by the dues of its members.
