Apparently Ozzy's business manager (his foul-mouthed wife), didn't like some of the things Dickinson had been saying about the whole Ozzfest Tour and someone in their camp organized the "attacks." Picked some info. up here:

Including this great quote from Dickinson:

Bruce declared 'You'll never hear MAIDEN on U.S. radio, MTV and certainly never see them in a reality show,' he says they will play 60 minutes, not 55.
