The closed info loop isn't restricted, or small. Even if you trued to verify something it's an huge ecosystem of FB posts, blogs, You Tube, X/Truth social, podcasts, local radio... I don't know how it ever gets fixed, because there is so much out there now, it's a whole evil alternate reality.
Have fam that recognize that “phones know everything about you” but can’t see they’re being influenced. They believe YouTube a neutral site and a purveyor of truth b/c they think themselves aware, smart and in total control of the misinfo dished out on the internet cess pool of targeted algorithms.
