Things that are true are easier to explain and defend than things that are false.

I see misinformation as kind of like pushing on a string, you always risk damaging your credibility and even (accidentally) illustrating that certain ideas or ways of thinking don't actually make sense, and then you don't have any impact any more.

So eventually there are opportunities for other people to fill the void, even if themselves imperfect, cause they can use a slightly more truthful paradigm as a practical way to gain traction, even if they don't necessarily have any noble feelings or motivations. And under the surface there are always people who only care about what seems true and real.

So the trend is always towards more true beliefs winning out, with maybe some hiccups of one step back and two steps forward along the way.

The fake news thing is funny, because if people are spreading bad information it will extinguish itself over time. There's never a need to censor, and the more we censor information into only centralized sources, those sources would in time become very fake and manipulative, even if they weren't initially.
