> Why do you think anyone should be in the position of "determining" the information that is being seeded? Fight disagreeable speech with agreeable speech, amirite, but don't yearn for a boss to tell which is which.

Maybe the more exact word for what I mean is "discern" rather than determine, though determine works fine too ("Officials are working to determine the cause of a bus crash").

Anyhoo, I don't yearn for such an arbiter.

>don't yearn for a boss to tell which is which.

This is not what is being said - I will quote the parent commenter:

"Here it seems that an influence / behaviour change campaign could be waged relatively cheaply against a relatively small number of people, exist completely outside the normal rules for fact checking or veracity, and the majority of the population would have no idea about it."

This is talking about being "bubbled", and how different collections of people are seeing completely different things, and because both sides don't know what the other is looking at, they become alienated from each other.

Furthermore, there is another problem - while a singular lie can be countered, a thousand different lies told to a thousand different communities is much harder to defend against.
