I never said Kishimoto was upset about what i'm saying it that people as of late have been suggesting Naruto's success was purely because of the editor and not Kishimoto himself. All jump mangaka have editors to provide input into their stories it's a prefectly normal part of the process and it doesn't mean the work isn't the product of the writer himself.Yes, but Sasuke was added because Kishimoto was having trouble plotting out the story without him. So his editor suggested a rival. So Kishimoto wasn't upset about the addition, he said it became easy to plot out the story having Sasuke.
