I agree with you that what youtube is doing now is not censorship by any standard definition and I don't think it's a bad thing. You might be able to argue that it's a form of "positive censorship" in the sense that a wiki on a video would be a scarlet letter but even that seems like very weak censorship.
I included the example of copycat attacks to show good faith that I'm not ignoring examples I know of that counter my own argument. What I'm trying to understand is the role of radicalization and conspiracy in violent acts. We know there are large communities of radical conspiracy theorists and yet physical violence or violent harassment is only a small subset of that community. How safely can we presume that "radical media" is the main cause of the latter violent groups? It's definitely an appealing narrative to imagine these people groom and reinforce their own beliefs until they "boil over" into violence but is that really how it works? We act as though people can be almost brainwashed into doing terrible things just by mere exposure. I'm arguing that at the very least it's more complicated than that and we should inject a little bit of nuance into the rhetoric of what conspiracy theories mean for society.
