Cordycepted

Being "Cordycepted" is when a person, group, or organization is taken over by outsiders, usually political activists, and their original culture, mission, or goals is replaced with the outsider's political culture, mission, or goals, often self-destructively.

The name comes from the "Zombie ant fungi," Ophiocordyceps, which is a parasitical fungus that infects ants, literally forcing them to go to a high location and become a spore bomb to infect other ants.

The specific tactic when outsiders join a group to do this is called Entryism, and is a hallmark of political activism going back since at least the 60s. See also "Spectrum of Allies Analysis," a specific activist tactic that seeks to push a person, group, or organization "just one tick" in a certain direction, from "active opponent" to "neutral" to "active ally," often from outside the group.

While this is a primarily political or culture war thing, many artists also become cordycepted by fetish communities, particularly those who accept commission work. Artists who find a specific niche of commissioners or fans may find their work shifting to cover this niche near exclusively.
