“Conspiracy theory” is a CIA-coined term that since the 1960s has become a well-used and effective disciplinary device that has been overwhelmingly useful in defining certain events and areas of inquiry off limits to debate and imputing insanity on the part of the proponent. Especially in the United States and today raising legitimate questions about fanciful "official narratives" is deemed a major thought crime that must be cauterized from the public psyche at all costs. Infra, please find the official document and directive that got the how shebang roaring out of control.

Language policing is not just something that Social Justice cultists do. They got it from far superior practitioners, and the Intelligence Community (with its long-standing ties to Wall Street and Madison Avenue) is one of them. Shaping how populations think by shaping what words are used and how, culling the propagation of some ideas while supporting others, is literal mind control (via control of information, particularly how one is able to process and pass on such). Memetic warfare allows one to shape the field for control over the Moral Level of War, through which all lower levels becomes much easier to wield.
By using kill-terms like "conspiracy theory", the memetic poison works to tip the memetic level to the advantage of the poisoner, acting in metaphorical terms to the language-triggered parasites of Metal Gear Solid V: The Phantom Pain- to put the speaker into a Sophie's Choice of silence to survive or (socio-political) death for speaking out. "Thought Crime" is hardly a non-issue now, and this video shows how this became a thing in the US (and, you can count on it) the rest of the West; what was formerly said to be only a tell of a cult (such as Social Justice) is now revealed as something the Globalists did first (and A/B tested since World War 1 into its current form).
And yes, the Internet did wreck shit for the Globalists; that is why they want control over it so bad.
