The theory of "Spirals of Silence" is related and explains a lot of the complicity and collusion by people who disagree but do not voice dissent:

The concept of "Luxury Beliefs" has a bearing:

Status Spirals
"The economist and social theorist Thomas Sowell once said that activism is “a way for useless people to feel important, even if the consequences of their activism are counterproductive for those they claim to be helping and damaging to the fabric of society as a whole.” The same could be said for luxury beliefs. They are similar to luxury goods, but present new problems. Attaching status to luxury goods or financial standing meant there were limits to how much harm the leisure class could do when it came to their conspicuous displays. For example, fashion is constrained by the speed with which people could adopt a new look. But with beliefs, this status cycle accelerates. A rich person flaunts her new belief. It then becomes fashionable among her peers, so she abandons it. Then a new stylish belief arises, while the old luxury belief trickles down the social hierarchy and wreaks havoc."
Cameron Hardwick makes an interesting argument for "Piety Contest" being a better description for what is often called "Virtue Signalling". He also suggests that "Piety Contests" are much the same as "Purity Spirals":

THE CREATION OF DEVIANCE by Jason Manning

"The way institutions define right and wrong has more impact on the rest of us than what Crazy Bill the local barfly thinks about things. For one, the opinions of organizations and their experts carry more weight"
(Article ends - my bolding)
" . . . when an institution identifies something as offensive, it will tend to lead to more people taking offense, whether genuinely or cynically. We would thus expect to see broader change in conflict and social control.
A final point of interest for those who study deviance and social control: As sociologist Kai Erikson observed, the agencies charged with preventing or policing deviance can be the very ones that create it. To give an extreme example, the witch-hunters of Renaissance Europe were quite good at creating witches — by torturing accused witches into both confessing and then naming accomplices, the witch-hunters created an epidemic of witchcraft accusations, and thus a need for witch-hunters. Witch hunts are an extreme example, where the offensive conduct is imagined whole-cloth. But milder versions of the same phenomenon might happen wherever those charged with combatting deviance engage in campaigns to ensure that everyone agrees with their mission, or to expand the range of deviance they’re in charge of controlling. The activities of university administrators may also fit a larger pattern, one in which agents of social control readily create the need for their own services."
I am sure we can all think of examples of public funds being showered on organisations eager to exercise social control, along with dedicated funding for the policing of "non-crimes" (while at the same time a massively depleted police force lacks the resources to deal with actual crimes).
