That's capitalism. If the opposing teams can afford it. The funds one get will help R&D to get better stuff, as long as it's not illegal or cheating. That's the fundamental basis of improving and progressing to better things.I love that idea. All the high tech gear that was developed to help your athletes win should be made available to others. Gotta help others win too. Make it fair you know.
Unless you feel sports gear is national security and should be restricted? If a country is confident in itself, it wouldn't care about selling such sporting equipment.
