No, it's a feature of the human mind that truth is considered objective independent of the lens used to acquire it. "Post-truth" sources in some arenas will be conflated with "real-truth" sources in others, leading to a blanket demotion of the perceived value and quality of truth. The whole argument from TFA is about human psychology, not about specific offerings of "marketplaces" where truth may be more or less maligned.
