Your definition of journalism is a bit distorted given the current journalism environment as an example. The current scene is that all journalists have editors who comply with their editors and the editor's backers (institutions or private organizations, CEOs, Managers, Lobbyists, Political Parties, financiers). These editors are playing the politics game, not the journalist game. Initially Wikileaks was actually mediating whisteblowers and big publishers, but big news organizations werent publishing what they were sending them because it didnt work with their narrative. The military docs that Wikileaks published were first sent to New York Times, however, NYT didnt want to publish the files at all, they werent even excited by them.
