A problem? He didn't like him for being disrespectful.
I'm sure that where Jay comes from getting a corporate type punishment is extremely lightweight to what they do to disrespectful nikkas in the street game.
So Jay didn't like him, Cam didn't like Jay. But Jay was Cams boss and Jay still let Cam earn cause the money Cam generated went into Jays pockets and he had better things to worry about. Then Cam and Jay separated and Cam got even more disrespectful, Jay (allegedly) didn't fukk with it and had to (allegedly) teach him a lesson. According to Cam Jay even sent someone to shoot him

. If someone is running around snitching on your murderer attempt, putting a leash on that dog is only right.
Also it just seems like none of Jays people ever liked Cam from OG Juan, Chris Lighty (and his brother), Puffy, Lyor Cohen and more.
And he dissed Jim Jones as much as he dissed Cam'ron, didn't mention any of their names. Except that he said "The Joneses can't keep up".
