I think the hangup people have is when they see apparent orchestration, groups of people making moves that seem coordinated, they assume that conspiracy must be the explanation.
But we know from nature that this needn't be the case. Look at a school of fish. There is no hierarchical command structure, nor any democratic council of the fishes, or anything like that. Their schooling behavior is emergent behavior from each individual fish following more or less the same rules as the other, coded in their DNA. They take cues from each other, go with the flow, but they're not actually conspiring with the other fish. There is no Fish Illuminati, just a bunch of fish doing normal fish things.
The failure to recognize the possibility of emergent (or convergent) behavior in humans is I think the root cause of many conspiracy theories. This is related to the concept of pareidolia, e.g. seeing patterns when there are none. In this case there are genuine patterns (fish clump up in schools) but the explanation offered up for this behavior is erroneous (fish Illuminati.)
