The legitimacy of journalism as a truth-teller has become contested during the era of digitalisation and newly emerging platforms. Recently, the epistemic authority of legacy journalism has been challenged by right-wing podcasting. This article explores metajournalistic discussions on the identity of legacy journalism as a truth-oriented practice and institution in six Finnish podcasts published independently outside legacy media on YouTube. This metajournalistic discourse of truth is identified through topic modelling in 229 podcast episodes, of which 119 are scrutinised using qualitative discourse analysis. The discursive articulations in the YouTube podcast episodes are assessed in the light of realist and antirealist philosophies as well as epistemic theories of journalistic truth structured by critical realist and pragmatist philosophies. The results show that the epistemic authority of legacy journalism is challenged through three interconnected themes through which legacy journalism is articulated as an antirealist practice and institution. By contrast, YouTube podcasting is framed as a platform for a balanced, authentic, and uncut talk that realises the epistemic ideals of journalism. The challenges to the epistemic authority of legacy journalism presented by the Finnish YouTube podcasts are also similar to those identified in previous research on right-wing podcasting and online counter-media. The findings point to the need for legacy journalists and podcasting practitioners to adopt more nuanced and context-bound understandings of journalistic knowledge and truth structured by critical realist and pragmatist philosophies.
