I think it means more than that. The Straight Dope concludes its article, after debunking the "there was no moon landing and it was all filmed in the Nevada dessert" theory, by saying:

"There will always be people who claim a conspiracy for just about anything. Facts will be ignored, rational people will be amazed and dismayed. And Cecil will continue to try to fight ignorance, against all odds."

My sense is that THOSE are the conspiracists.
