By cost of publishing I mean effort involved in creating content to be published as well. Conspiracy theories thrive when credibility and authority are not required to publish: flat earthers, anti-vaxxers, government related conspiracies, aristocracy related conspiracies... People being able to post anything also facilitates "online mob justice", when people mistakenly arrive to the conclusion that certain entity is responsible for whatever they consider unfair.
