I am not in Chipmixer campaign but I don't think any member of the forum is aware that the company is promoting money laundering or other illicit business transactions as alleged by the FBI and others. I am sure many participants would have left the campaign if the are aware of these allegations. These members were paid for the legitimate service they rendered to the company, hence there is no legal justification for a request to pay back what that have earned until it is proved that these members are aware or part of these alleged crime.
