Trump threatens to 'close' down social media platforms

It really isn't about fact checking. No social media company is in position to do so, especially when dealing with unknown. It is about blocking the message, which IMHO is the same thing as tired old deplatforming. I am not taking sides here, but would it not be fair to have every journalist and politician who keeps tweeting about the Russian collision marked for fact checking or banned now that "official" sources disagree?

That would be hilarious to watch. Unfortunately we all know that’s not happening.

If companies want to allow user generated content they should be liable for moderating it. The legal protections that these companies have thrived on should be repealed. They don't seem to have trouble removing content they disagree with so illegal content shouldn't be any more difficult.

nobody is in a position to declare any fact truth. it's impossible almost by definition.

that doesn't mean that it isn't possible for some facts. in fact, i believe social media are among the best positioned to do so for surprisingly many facts.
