> I wrestle with understanding why most media are anti-Trump and anti-oligarchy,

Who told you they are anti-oligarchy? They are most definitely pro-oligarchy, they are just upset the power is not in their (I mean a person from their peer group) hands. Compare media behavior when the control belongs to "their" and "opposing" party, and you'll see a stark difference.

> and the oligarchs are still able to control those media's use of 'left' and 'right'. How does this work?

They are the oligarchy. Talking heads on TV are part of the system. There's no some struggle to control them and bring them under the toe of the oligarchy - they are a body part of it. Nobody wonders how a man manager to control the fingers of his own hands - it's his hand, of course he controls it.
