The fact that so much money was given to private corporations, in secret deals outside any legal proceedings, on unproven products, all while censoring any critics, really gave the conspiracy theorists water for their mill.
I believe they would have had a much harder time spreading their misinformation, if they couldn't have the street cred of having "the system" against them. That is, if we had the voice of doctors vs random loonies, instead of our respective corrupt governments vs anyone they're trying to censor.
