Like you said pwi in America is a susidiary of those in Korea, but in difference that Koreans have full right to it and only they can fix anything, if Steve is COO of PWi that it means he is a translator and can talk with them to make this game better. Still license for PWi here is one thing, fixing bugs is another, the license is only given prolly to host the games or make contracts with other hosters which may host as well, like PH rohan.
Private server means one, that his "mother" (main game) sucks so badly that players need to configure the game and make it more and fair balance. But still instead of sending those DMCA of stolen source of the game code they should fix their main game here, so the privates could stop one day.
