Let's be clear: Reach matters.
In Denmark not so long ago we had a right-wing extremist named Rasmus Paludan running, who for a while nearly dominated political coverage & was almost elected for the Danish Parliament - until he was deplatformed from his primary channel, Youtube, for hate speech, at which point he virtually disappeared from the public eye & hasn't been able to stage a comeback since.
Acting against #propaganda channels is a matter of democracy.
