The article does point out: "Not many members of Team USA actually train there. In 2012, a study by the Athletes’ Advisory Council — a group of current and former athletes — found that just 13 percent of Olympic Training Center usage went to U.S. Olympians."

That doesn't actually say how much the Olympians use the facilities, but if we accept that relatively few do then the money isn't going where it's intended even when it is spent on infrastructure.
