Imagine if you are a political candidate (republican or democrat) and you are discussing your policies with a potential voter. In “managing their network” Comcast finds that it can cut its traffic in half if it only allows one party’s political traffic through.
Or, what if you are doing business on the web selling Coca Cola, but Comcast has done a deal with Pepsi and disrupts all internet traffic affecting Coca Cola Sales. Far Fetched yes, but what’s to stop this now that they have made a start.
Maybe a rival hosting company does a deal with Comcast. Suddenly CrystalTech Users find that their customers’ transactions are being disrupted.
Where does it stop?
You sign up with Comcast, but Comcast has the right to say who you can talk to and what you can talk about, is that what we really want?
