It's sort of the equivalent of when Noam Chomsky says, "sure, JFK and 9/11 may have been carried out by organized conspirators within the U.S. government, but it doesn't matter and there's no point interrogating it because it makes no difference from a policy perspective." In the cases where it's not outright disinfo it's a psychological defense mechanism, a way of ceding the bare minimum of ground to the conspiracy theorists which is demanded by the mountains of evidence, while still hiving it off from the rest of one's worldview.
