This would be like if you found out the local little league basball had been sold. It's a community resource that only exists through the continued donation of time by the members. It's not something that should ever be "owned".
If he didn't change anything for the users (kids and parents across the US), but cleaned house in head office and installed his own management team, the local teams would continue running as they always had. The owner really would benefit from the goodwill of the community and really would "own" it in a meaningful way. Some grumbling idealists would start a new "really truly non-profit" competitor, but for most people the friction of switching would be too great. But if he interfered too much and made the players' experience worse, people and teams would find it attractive to move to the new competitor.
