Jack's "earned not bought" effectively means that Twitter's opaque & self-serving algorithms, rather than explicitly disclosed prices & targeting, will control what political messages get "reach" on Twitter. Twitter's bullhorn will thus only be available to those people and messages that Twitter likes. Those messages that Twitter doesn't like will be algorithmically confined to a unlighted cellar, for display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard'.
