Gyönyör wrote articles for the Új szó newspaper from 1968 onward. In his articles he analysed the situation of the Hungarian minority.
Šimun Šito Ćorić, a Croatian theologian, writer and psychologist, collected interviews and texts by some of the most important Croatian dissidents (Marko Veselica, Vlado Gotovac, Franjo Tuđman, Petar Šegedin, Ivan Z. Čičak, Ivan Supek, Zlatko Tomičić) in 1983 and published them in English in the book So Speak Croatian Dissidents. He attempted to warn the world public about the unenviable position of Croatia in Yugoslavia, and especially the unfortunate status of persecuted Croatian dissidents. Most of them were sentenced to prison sentences after show trials. The author published the book under the pseudonym Boris Katich because he feared the Yugoslav secret service would retaliate against him (although he was then living abroad), or his family, who lived in Yugoslavia.
In his introduction, Ćorić wrote about the "Croatian question" in Yugoslavia, reflecting on the position of Croatia in the Yugoslav federation and presenting the ideas and demands of Croatian dissidents. He wrote short biographies of the dissidents, particularly emphasising the reasons why the communist regime persecuted them. The book included Franjo Tudjman's paper "Croatia in Yugoslavia," and Tuđman's response to the indictment filed against him by the District Court in Zagreb in 1981; the interview granted by Ivan Zvonimir Čičak to Swedish television, which was also published in the German newspaper (Der Spiegel) in 1977; two interviews with Vlado Gotovac by the Swedish and Dutch media; an interview Petar Šegedin granted to Swedish television; part of Ivan Supek’s book Krivovjernik na ljevici (Heretic on the Left); the article by Antun Nizeteo on the Croatian poet and dissident Zlatko Tomičić, and seven poems by Zlatko Tomičić. The book was released by the publisher ZIRAL in Norval (Ontario, Canada), and was published in two later editions.
In the issue from 15 December 1950, the Croatian expatriate magazine Hrvatski dom published the article “Nacionalna politika Komunističke partije Jugoslavije u svijetlu borbe hrvatskog naroda za samostalnost” [National policies of the Communist Party of Yugoslavia in the light of the Croatian people's struggle for independence] by émigré Adil Zulfikarpašić, written under the pseudonym Aziz Čengić. Zulfikarpašić was a friend of Augustin Juretić and his associate until Juretić's death in 1954. It was Zulfikarpašić, together with Msgr. Pavao Jesih, who took over the magazine Hrvatski dom after Juretić’s death. The two of them edited the magazine until the last issue in October 1958.
In the article, Zulfikarpašić (Čengić) described the development of the national policies of the CPY since its establishment after World War I until after World War II, and concluded that "the theory of free nations of Yugoslavia, even with the constitutional right to secession from the union, is a façade – in reality it is rigid centralism carried out from Belgrade through the Central Committee of the CPY (Hrvatski dom, 15 December 1950, 2-3). Zulfikarpašić published a similar article, "Political report on the situation in Yugoslavia," in the newspaper Hrvaska riječ a month later (No 1-2, January-February, 1951). Similar analytical articles dealing with the issues of communist ideology and criticism of the communist government in Yugoslavia were published in Hrvatski dom continually in an attempt to influence the attitude of Western countries and their public opinion of Tito's Yugoslavia.
The manuscript of the article " National policies of the Communist Party of Yugoslavia in the light of the Croatian people's struggle for independence " is held in the Augustin Juretić Collection at the Pontifical Croatian College of St. Jerome in Rome. The collection also contains a printed version of the article published in Hrvatski dom.
