Why does almost everyone have to make such a big deal about the whole Viva La Vida Joe Satriani If I could Fly thing?

Joe Satriani and "If I could fly" fans feel threatened por coldplay and "Viva la Vida" fans cause they will lose all of their reputation so they go to coldplay videos and write hating comentarios saying that its copied For example how often do tu see someone saying this artist originally wrote this? Rarely... So i say its all bullshit and coldplay never copied Joe Satriani...
