I'm not sure whether this holds much merit in reality as it is purely speculation, but I'd strongly suspect that a great deal of modern popular conspiracy theories are designed and initially propagated by PSYOP groups to influence and control certain aspects of reality for whatever intended purpose (that's kind of the essence or purpose of a PSYOP) - like for example, preventing Bill Gates' eliminating third world poverty or whatever his goals are. Some of his philanthropic work will quite possibly have a snowball effect on a certain areas that some countries won't like which would give rise to misinformation campaigns to sabotage and hinder his work.
