Based on my experiences at protests, the main threat posed by right-wing vloggers is that they record interactions with unsuspecting participants, “interviewing” them, and then post the videos online to mock and/or doxx them. Blasting copyrighted music effectively shuts this down.
For videos of violent incidents, you can generally mute the video without losing much, so I’m not too worried this will backfire in the way you’re suggesting.
