Greater Greensboro

Robert Bell writes about Greensboro improving its position and how the event gained an August date in 2007. This paragraph caught my eye, though I'm not sure what exactly it means:

It wasn't enough that Greensboro's tournament officials had redesigned aging Forest Oaks Country Club. Now the PGA Tour was pushing for its tournaments to become tax-exempt organizations run by a board of trustees of top businessmen from each tournament's respective city. Without these changes, Finchem said, it was unlikely Greensboro or any other tournament would be around when the tour prepared its 2007-2010 schedule.

Can anyone explain the desire to shift to "tax exempt organization run by a board of trustees of top businessmen?"  I'm sure it's strictly in the name of charity, but you know, it's good to double check.
