The Big Lie in the denialist movement is that independent youtubers, bloggers and so on are completely uninterested in ratings – indeed, anything but the sacred truth. That they are not inhibited by numbers of hits, advertising, and the generation of forwardings and references according to the content of individual posts, in the way cable companies and “corporate news” supposedly is.
The corporate news media is certainly interested in how many people stay on for the next segment, and through a set of adverts, and usually they’ll wait 24 hours for the data to come in. With these independent postcasters/youtubers, they are intimately familiar with the results, pretty much in real time. Lifetime experts on the subject wouldn’t be putting out the number of episodes on vaccines and their effects as these people.
It takes a fair amount of gullibility to imagine that the “vaccine scepticism” isn’t being driven by hits by these supposed independent commentators. They want response. Suggesting that the scientists are pretty much correct, given the current data and understanding at any point, just isn’t going to get the response these grifters crave.
