The comment could also be about how they each view how the Matrix should be. I'm having a hard time coming up with a way to explain it, but how they see "the rules" of the Matrix.
What are their views of the rules of the Matrix?
The best way i can answer is that Puck wanted/wants a free and open matrix, being able to exchange info at will and accessable to anyone, and fastjack saw the matrix in a similar vein, but both of them viewed it in a different way.... Puck as a okuta/techno and fastjack as a hacker. Thats the best way i can explain it....
Hope that makes it a bit clearer
