There were plenty of Dale Gribbles in the world before social media. Movies and books were full of conspiracy stuff (see "Enemy of the State" from 1998), and the public believed lots of them to varying degrees. Overreacting to that by using government to silence/control them would surely only generate legions more and give them easy legitimacy as victims.
The existence of a fictional movie says nothing about how popular conspiracies are. I have seen a lot of dystopian movies and read such books, including cyberpunk. A Scanner Darkly, The Illuminatus Trilogy, The Matrix, Snow Crash, Dune, eXistenz, just name some random ones. I'll mention four series, too: Twin Peaks, X-Files, Utopia, Nikita. That doesn't make me a conspiracy nut, because I am able to differentiate between fiction and non-fiction.
The trouble from 80's is different. We've shifted power vacuum, but whilst doing so the rich have become very much more rich, and [generally] they don't want to take responsibility; they want raw power. Things like bullshit (lies, conspiracies, manipulation), drama (such as creating friction between poor and middle class), obliteration of facts and science, cryptocurrency to avoid sanctions and law, and criminal behavior (including methods to avoid paying tax) are each tools for achieving more of such power.
UFOs are one of such, too. They're a tool to accelerate the distrust in government. For the acronym UFO itself is broad. A meteorite or Starlink satellite could be mistaken for an alien spaceship. Furthermore, drugs, hallucination, psychosis and the power of suggestion alone are strong tools to feed such fables.
I am well aware fans of conspiracies can very well be fans of X-Files but it is fiction first and foremost, plus don't forget Scully's role and background.
Thinking that Starlink satellites exist to make people think they're UFOs and create public distrust in the government seems like a terrible conspiracy theory, though.
> Thinking that Starlink satellites exist to make people think they're UFOs [...]
These are your words, your interpretation. Not mine.
Moreover, the meaning of UFO is Unidentified Flying Object. That could be anything, from Starlink to a swarm of drones to a SR-71 to a meteorite or some fireworks. Or just someone's vivid imagination, LSD or opioid trip, lying in a death bed, hypnosis, etc.
