And you would be wrong...
Companies like Netflix are hogging the bandwidth that you would normally use therefore it costs the cable companies more money to upgrade their services.
Instead of passing those costs to Netflix [which is raking in millions] they will be forced to pass the coasts onto everyone [that means YOU pay more]...
The customer is the one using the bandwidth. If you use more you should pay more. Comcast is currently free to charge customers based on their usage of Comcast's product. What Comcast should not be able to do is restrict content from sources they don't like.
