I think it is probably something that mostly arose organically, and I think (maybe I wasn't paying close-enough attention) that that's consistent with the views of the guy in the video (in that it doesn't contradict what he says). I recall the vid describing the process, but not necessarily implying intention to it (see the description of the radicalization of both the host and his audience) except when he talks about people deliberately infiltrating groups (BTW, he links to
this, which looks like it could have been written by
@JamesRussler).
