I don't see "accuracy" or "lack of bias" in the benefits of podcasts for news list. These things are far more important than convenience, efficiency and certainly more important than "engagement."
Of course accuracy and lack of bias boils down to who is producting the podcast and who benefits from it- something you won't just stumble upon- you have to research it.
In today's "you, you, you" world, no podcast directory is ever going to try to discourage you from giving that most precious thing, more valuable than truth, justice or any of that other stuff: your attention.
