Just my opinion, but people predisposed to attribute events or activities to conspiracies often do so to bolster a sense of self worth, as in 'I'm important enough, or my cause is important enough, to merit an entire conspiracy by a group to oppose it'.
This can also arise from the tendency lately to characterize anyone who has an opposing view as 'evil'. I mean, we couldn't possibly be wrong, so anyone who disagrees with us must be a bad person. That goes hand in hand with the tendency these days to eschew self examination.
A good example of conspiracy fallacy was alternate energy vehicles. For decades, we have heard that the lack of non fossil fuel vehicles was the result of a conspiracy between the oil companies and the car companies. The few alternate energy vehicles such as all electric, were fairly pitiful, exhibiting the concept that one has to suffer to be green.
Then, along came Elon Musk, who built an all electric vehicle that people actually want to own, not because it's green, but because it's a very good car. After Tesla, the traditional car companies have done much better with alternate energy vehicles... now that they see the size of the market.
And so we learn the truth: it wasn't a conspiracy, it was lethargy and disinterest on the part of the traditional auto makers. That is an industry run by clods.
On the other hand, it was Henry Kissinger who once said - even paranoids have enemies.
