You are right that repressive ideological control is exercised by normal everyday communications between individuals and through media. It's not so much a conspiracy as it is a (frightening) natural desire to gain social respect by avoiding thinking and saying "stupid" things. Of course, the problem is that people are inherently ignorant of most things they are capable of thinking about, so for this reason there is fear of looking stupid and hence the tendency to avoid saying things deemed stupid by others.
Just something as simple as the label "conspiracy theorists" works as a prod to dissuade many people from entertaining or exploring thoughts or ideas that remotely smell like they could be attacked as being a "conspiracy theory." It is not some form of mind-control in the sense of UFOs or government using special brain-wave controllers to directly manipulate nerve cells. It's just a culture of self-discipline that spreads among individuals.
You could call it "anti-conspiracy repression culture" or just "the tyranny of subjective realism."
Sane people would just look at pictures and discuss reasons why they think it is possible that those could be buildings or natural occurring rock formations. There's really no need to go accusing each other of paranoia, hoax, lies, etc.
Science is basically supposed to be an open discussion of facts and reason where interpersonal emotional manipulation is avoided.
