I think it is the timing of this exclusive R&D that is annoying some people. However, it is also a gamble for sailors who use something a little new and different. If none of the three boats using the new sails win medals in the Olympics, it will be a non-issue. If they do, it will probably be an issue forever, because it provides a good excuse for the losers.

It doesn't sound to me as though they have done anything illegal or unethical.

I don't know whether there are any restrictions about track shoes, but if I were a track star, I know I would be trying to design a faster shoe -- just for me.
