Truthfully, they probably make more bred xi's than any free run. It's not the supply that's the problem...it's the demand. WAAAY more people want the XI's than the frees. People see it as a "golden ticket" shoe...a shoe that can get them any other shoe via trade...a shoe that is worth its weight in gold in the resell market. So yes, there are MANY people that hoard XI's. It kind of sucks for the people that want them, but it is the way things are.
Truthfully, I understand the situation with people who want a pair and don't have them, but honestly, I do feel like if you REALLY want them, you would have gotten a pair. It's not like they aren't available...
