Trump threatens to 'close' down social media platforms

Can this even be considered a free speech issue? They aren't deleting his tweet, only displaying it alongside a fact check. Of course you can try to call into question the impartiality of the fact check but that is a long way from not deciding not to show the content.

And if he decided to "close" Twitter, it would actually be a clear case of censorship from the government and a violation of free speech.

Twitter is merely labelling a tweet as being factually incorrect, it's not hiding the content.

I think it really depends on what you view twitter as. If it's a communications platform, like your phone, then yes 'merely labelling a tweet' is as troubling as your phone company deciding to shut your call off when you mention to a friend that you're going to vote for Biden. If Twitter is a publishing platform, then it certainly can expose its editorial bias, but one must really consider whether or not it should have to pay its writers.

> "shut your call off"

I fail to see how those two are equivalent, shutting off would be removing the tweet, they did not do that. Labeling something is not equivalent to censuring the tweet or cutting off communication.

Warning users is similar to phones letting you know they think a caller is spam.
