In 2012, Gustavo and other progressive journalists founded Centro de Medios Independientes (cmiguate.org) as an alternative, independent media platform to counteract the disinformation put out by the mainstream press and to oppose attacks and censorship against those working to defend their land, their livelihoods, and for human rights. In 2013, he began working as a political analyst for the respected human rights group CALDH, that represented the survivors in the national case of genocide against former-dictator Efraín Ríos Montt.
