It is the opposite really - opinions are some of the least controlled they have ever been as reach is far equalized and means of control at a low. It is one of the least conquered times.

Hell the idea that they can even 'control the attention' is a fallacy that assumes they have active knowledge of what their content will do like the New York Times has an editorial control. It is like the idiot congresspeople who spent their question time complaining about their negative search results for their name.

Even the heaviest handed management would fail to exercise the level of control as an editor of a scientific journal who knows absolutely nothing about the underlying field.
