It's nothing like that. It's clarifying the definition of a group. The set of people involved in "the media" are, by definition, in the business of creating and publishing media (news, opinion pieces, entertainment, etc). Success in this business does not require keeping the public informed, but it does require selling content. Thus, the group as a whole is in the business of selling content, and not necessarily in the business of keeping the public informed.
