I think David Icke is like, controlled opposition as they say.
I mean if you wanted to push something through that nobody would want, your best bet is to feed info to some crazy guy who thinks the Monarchy are Lizard people and get him to tell the public about your plans, that the elite institutions want to roll out mandated vaccines and a cashless society. Then nobody will believe its true however much they say it, and after its implemented, people will constantly defend it or else it looks like they agreed with a crazy guy.
