Comcast has a history of being a video streaming/television company. The want to be a television company. The problem is, their customers don't want them to be a television company, they want them to be a utility: simple, reliable and commoditized, like electricity and water. They have the natural monopoly (wires and rights of way) that makes a utility, and internet access is a utility in the same way electricity is. But video streaming is naturally competitive and the only way they can have an advantage there is by sabotaging their utility side.
