Such platforms should probably not be permitted to promote in a general and unrestricted sense the content of particular speakers that make use of them. That's no better than clandestine government propaganda. An obvious wolf in sheep's clothing.
The answer is we decide what is disinformation through our institutions and the value we place on them. Your and I's opinion on certain matters should never weigh remotely as much as an expert's on a particular topic unless we are such experts.
We ought to measure the value of one's speech through the scrutiny it has to go through to be published at trusted channels.
The public square is not in and of itself a trusted channel so I doubt you are talking about the same thing as the person you responded to.
Well, I don’t.
