Obviously you don't understand the basics. Hacking is modifying code to gain an unfair advantage in a competitive standing, which is also known as cheating. Justifying cheating as something right is an even larger commentary on today's society.
If Gree refuses to ban and enforce policy against hacking guilds then by their actions they support hacking. So why not cheat? Cheating to win at a video game...way to go superstars.
