Once upon a time, we had a functioning FCC that was contemplating the difference between content and infrastructure. The goal of an infrastructure business is to provide the best service to end-users. The goal of a content business is to get end-users to look at their stuff.

When you combine the two into one business, that business inevitably increases profits by reducing the quality of all services that do not lead directly to their own content.

Make it illegal for content businesses to own infrastructure businesses (and vice versa) and the need for other market regulations drastically decrease.
