If later on, they would see the Riders as a resource to get rid of anyone who want to completly destroy the world. Since there's no profit in a ruined planet. Right now they've only supported Museum & the Horoscopes. However it would be something if they also back good orginizations as well. Because that would make them very complex than the typical evil orginization.
