This is one of the reasons that the cable companies WANT to go from “product providers” to the conduit (just internet providers.)
The customer service infrastructure is expensive and the margins suck. Building a plant that provides high speed internet is simple and clean. Let the other guys (Hulu, YouTube, Netflix, etc) deal with the screwy billing, the complaints of content, and all of the other overhead.
Yeah, the cable business sucks. Having to buy channels, usually in packages, which force you to make tiers, that actual paying customers hate, and then those networks constantly raise their rates, which the customers hate, and everybody thinks they put the shows on, and all the equipment you need to maintain. Yeah, crappy business to be in. Nothing but headaches.
