I would not hold my breath, if I were you. Even if you got to see some "hard data", how could you be sure it was trustworthy? I am with you, I would like to see how it increases their cost, but I am sure we all know the answer to that question. If we do not, let me assist you with it.
When looking at a customer by customer basis, a little more traffic flow does not increase cost. It is like a cellular customer talking a few minutes past their allotted plan minutes. A few minutes for that one customer does not hurt them, as it is just extra airtime and minutes cost the companies nothing to make.
The problem comes when you look at entire markets or total company customer bases. You can only fit so much data down one pipe before it gets log-jammed and you have to improve your network. Of course, I do not believe that ISPs have reached a saturation point, but I do believe they have looked at the data and believe they will lose profits due to their procrastination on improving their networks. Due to this, we(the customers) are made to suffer.
Time will tell and we will just have to wait and see what happens in the near future. My guess is, sadly, that this issue will only get worse. I would like to be proved wrong, but I doubt I will.
