Society as a whole maintains it. As long as not enough people object strenuously enough, it simply doesn’t get discussed and continues on the way it is - that’s pretty much the definition of status quo, “the existing state of affairs”.

I doubt that. What’s an example? Objectively, the existence of a monarchy is opposed to the ideals of an egalitarian society. Any discussion of a monarchy’s mere existence without covering such topics serves to reinforce the status quo - it normalizes its existence and lies by omission about its negative impacts.
