@telexen: That's the same internet plan I have. Along with the emails suggesting that I upgrade to the next highest plan, I have also had the a Terms of Service "reminder" load a couple times when I opened a new browser window.
They made things worse by switching the cable to a digital signal, requiring a cable box if you want to watch TV. You get 2 basic boxes free and have to pay for extra boxes and pay more if you want DVR. So, on the TVs that arent connected to a box, were going to be watching a lot more streamed movies/shows and using up even more data.
