His thread references the "debate" over climate change, and his point is that the debate most people participate in isn't truly a debate over facts, but rather a debate over trust. That matters of complexity are too distant from any one individual to have direct exposure-to, so in order to form a comprehensive viewpoint on anything, one much choose whom to trust. And that it's this part of the process of "understanding" which has been exploited. That people have been encouraging people to trust untrustworthy sources for information which doesn't necessarily square with the scientific evidence.
In this light point, when facts are irrelevant -- and if fake videos are used to compromise the voices of those which deserve our trust then I fear for those advocating fact-backed positions. It's clear they'll face an uphill battle.
