So nothing the playerbase does can change anything?

The only thing the playerbase can do is vote with their wallets.
After GMS suffered a large loss of players and money, much of Nexon America's staff, as well as its corporate attitude, was replaced, by Korea's orders (I think?).
I don't know whether Nexon has that kind of power over AsiaSoft, but they can rescind their Maple license if they don't pay nice profits to NexonKR.
