Yes, they're all the press. For every instance of corruption you've listed, the outlet in question can still report on something else that others won't. That's the marketplace of ideas. Attacking each one for being imperfect on its own diminishes the chances that a given piece of information will be reported in the future.

Now of course that doesn't mean you should blithely believe what they say, or think you're getting the whole picture from any one. But they do all collectively form the press.
