>why the narrative is continued by individuals
Remind yourself of the tiktoks: they're a form of outward-facing propaganda. The point of propaganda is to inculcate some message in the public. If that succeeds, the people who carry this message "with" them will spread it themselves, since they believe it. If they spread it to other, they might get them to believe it too, though in that case, the message will have come from an individual, not from the corporation.
From the point of view of those people, it's just "common sense" or "what my father told me, and he was a good man". He was, but he was being used as a carrier for someone else's message. Your mailman might be a good man too, but that doesn't mean that the contents of every letter he delivers are true. What you're seeing is all the residue left from past propaganda (not necessarily corporate), sloshing around in society, spread around repeatedly.
