What they mean is that they are willing to give up $N you are currently playing to AT&T in exchange for $2N in new charges to the companies you are interacting with over the internet, who will pass that cost back to you, increasing your charge from Netflix, etc., from its current $X to 2N+X. So, you'll be paying more to AT&T in total, but less directly.

Of course, they'll use the additional money to offer you similar services to the ones that they are charging other people to provide you, and they'll offer you a lower price than their competitors can in the face of AT&T tolls -- say $X+1.5N.
