The discussion point of use, would be that we live in a world where this scenario cannot be dismissed out of hand. It’s no longer tinfoil hat land. Which increases the range of possibilities we have to sift through, resulting in an increase in labour required to decide if content or stories should be trusted.

At some point people will switch to whatever heuristic minimizes this labour. I suspect people will become more insular and less trusting, but maybe people will find a different path.
