I get your concerns. I am just spitballin’, but if each form of social media had its on “community notes” and then that was occasionally audited, that that would be a good start.
I think opinions are fine on both sides, but if comments like “tourist are 3x likely to be assaulted in Kentucky” were to gain traction, that hurts the people of Kentucky. There just needs to be stopgaps, like community notes, to stop misinformation.
I really hate to say the SEC would have a part in this, but some sort of entity has to have teeth to force these media companies to stop misinformation and to discern misinformation and political opinions.
