Yes, that.
Conspiracies have been documented enough times that it is totally valid to surmise that there's one in place at any given time, about any given field.
A quick inquiry to google on 'proven conspiracy theories' returned ten results just on google's AI. And it left out Iran-contra -presumably for the sake of brevity.
Sorry, to think there's a conspiracy isn't so whacky and unhinged as people want to make it out to be.
