A token can outlive the organization that created it.

ConstitutionDAO's original site says the 2021 project ended after losing the auction and assigns $PEOPLE no original-project governance rights beyond its ETH redemption mechanism. Separately, PeopleDAO says it later adopted PEOPLE for its own governance.

Those are different organizations and claims. Before treating a token as a vote, ask which body recognizes it and what the vote controls. An active exchange market doesn't answer either question.
