Comcast is in rent-seeking mode at this point; extracting as much money as possible from existing infrastructure.

By "infrastructure" I mean last-mile fiber buried/strung throughout neighborhoods and into peoples' homes. It's expensive to build such infrastructure, due to varieties of local laws, right-of-way access, and for the same reasons leaf nodes are most numerous in typical tree data structures.

So, Comcast's approach is to extract as much money as they can from existing infrastructure which they've built, acquired, or gained exclusive rights to, while directing minimal resources to building new such.

Along with that, they expend a lot of effort lobbying to protect that infrastructure from encroachment or competition by other entities, like other private ISPs, unbundling laws, municipal broadband, and the like.
