‘biased monopoly’ what are you talking about, everything is sourced and open
The heart of narrative control on Wikipedia is controlling what standards of evidence need to be met and what sources are acceptable.
An easy example of this would be the argument over adding an entry for Thomas James Ball to the List of Political Self-Immolations. Before they finally gave in and accepted it, there was a push to establish a standard for entries on the list that almost no existing entry on the list met and apply that standard to determine if Thomas James Ball should be included, while painting it as though the process were neutral.
