Any review of our ongoing coverage of Comcast will leave you with the impression that the mega-company is almost perfectly terrible at customer service, seems only interested in growing as large as possible as quickly as possible while tamping down anything resembling the potential for competition in its market, and has done everything in its power to kill net neutrality on top of it all. While many might believe that Comcast is getting killed by the same cord-cutting epoch causing so many others in the entertainment space to reach for the Tums, we recently noted that the cable company is actually still raking in money hand over fist. This is done, at least in part, by the company's subtle strategy of simply upping what they charge customers for internet services.

It's also apparently done in part by charging Comcast customers with installation fees for locations already tuned up on Comcast service.
