In January 2019, several Swiss newspapers published an article called "Der böse Jude" by The Magazin reporter Hannes Grassegger, about the origins of the world-wide campaign against Hungarian-born financier George Soros. A week later it was published in English as "The Unbelievable Story Of The Plot Against George Soros". In it, Grassegger draws on an interview with Birnbaum in which he describes how Soros was turned into a pariah in Hungary and a number of other countries due to efforts conceived by Arthur Finkelstein and himself. The article quotes Birnbaum saying "Soros was the perfect enemy... It was so obvious." Ahead of the 2014 Hungarian election, several right-leaning Hungarian newspapers published articles alleging a Soros-led international conspiracy against Hungary. Shortly afterward, the Hungarian authorities took legal action against the environmental NGO Ökotárs, claiming it was Soros-controlled. Although nothing tangible against the organisation was found, this helped to cement the impression in Hungary that Soros was controlling NGOs and meddling in domestic Hungarian affairs.
From 2015, the campaign against Soros intensified, culminating in a billboard campaign by the Hungarian government against Soros and the Open Society Foundations funded by him. In 2018, both the foundation and the Soros-funded Central European University decided that they would leave Hungary and move their offices to Berlin and Vienna respectively.
