I’d agree about not having broadcasts, but I think there is some merit about cutting out his cheering when taking out stormtroopers.

What you could do for this one:

In Finn and Poe’s first scene, when they are attacked by TIE fighters, when we cut to the TIE interior, we could hear that the Falcon is broadcasting one of Finn’s messages on open channels. The TIE pilot says as much and tells the other pilots to turn it off. It is basically Resistance propoganda, Finn sharing testimonial in order to de-radicalize other stormtroopers. Also cut Finn cheering when he destroys TIEs.

You could just add a line for Finn on the open comm:

Finn: “You don’t need to fight for them.”
Random Trooper: “It’s the Traitor! Shoot them down.”
