They did not want to be open about it

"They did not want to be open about it," 117 said. "I am beyond sad and RuneScape gold disappointed with Jagex and am extremely disappointed to find that after such a long journey and a long time, I'm unable to share this project with you. The mod of 117 doesn't seem to be in conflict with Jagex's policies for third-party clients, however the Runescape developer says that it's making changes to the guidelines over the next week, and will include references to projects that affect the look of the game.
