I'm thinking they do it because GUN and CUETE were both made almost totally from BEGINNING TO END to get Nortenos riled up about the cause. There is no official Sureno equivalent to this, especially one directed by La ~tu sabes~ with all profits going towards themselves as with GUN and CUETE to the Norteno higher powers. Surenos have plenty of albums out there of course, but name one that was created solely to unite them and dis the Norte. That's why they dont get targeted I.M.O.
