Conspiracies exist. Many are well documented, or at least documented enough to call out specific people for specific behavior.

A conspiracy mindset ignores those, and instead suspects conspiracy everywhere else, and usually without substantial evidence. Easy instances are detectable when the sentence goes they do something to harm us in a vaguely related way.

The latter is all over YouTube, and what influencers make money with. The former is sometimes reposted on YouTube after some journalists publish it in a serious media outlet.
