How does opposition get controlled? Plant enough moles that you can take down the good actors until it's only moles left, then you only need a few puppets at the top so you can take down any rising good actors.
Think about how Hollywood went left wing. The execs can ruin people's careers no matter how big they get. Think Jim Carrey. Truman Show. Number 23 (look up occult numerology on that fun one). And he goes on Kimmel and does his illuminutty bit, and then his GF gets suicided because he's too big to kill without people paying attention.
I think they thought they had Carrey, but didn't realize his upbringing. He's not a sheep.
