And instead of 1,000/mo of the very worst abusers getting booted, Comcast gets to boot many many more

2. Comcast may continue to notify any residential high speed Internet service subscriber whose bandwidth usage use exceeds the Threshold (as determined by Comcast in its sole discretion) that the subscriber's service may be, or will be, terminated as the result of excessive use. However, no residential high speed Internet service subscriber shall be notified of a breach of Comcast's excessive use restrictions unless the subscriber's bandwidth usage exceeds the previously disclosed Threshold.

This is the same system we have in place today. The only difference is that we will now provide a limit by which a customer may be contacted. As part of our pre-existing policy, we will continue to contact the top users of our high-speed Internet service and ask them to curb their usage. If a customer uses more than 250 GB and is one of the top users of our service, he or she may be contacted by Comcast to notify them of excessive use. At that time, we'll tell them exactly how much data per month they had used. We know from experience the vast majority of customers we ask to curb usage do so voluntarily.
