Today, Donald Trump issued an executive order regarding "censorship" on social media.

It's an interesting order. The core issue is that once upon a time, in a section of the Communications Decency Act, there was a provision that declared internet sites to be people providing a place for speech, as opposed to publishing content. In other words, my words here are not the opinion of ISF. ISF is just presenting a platform that I, and a lot of other people, can post in. They are not publishing my work, so ISF cannot be held to account if I say something bad.
The basis of that judgement is that they aren't picking and choosing what goes in here. They are just providing a platform.
As part of that act, media giants like Twitter (I don't know if it existed yet, but maybe Myspace would be a better example) would also be allowed to eliminate
"harmful" material, like pornography. Court rulings had said that if they edited data, removing objectionable material, that meant that they ceased being a public platform, and became a publisher, because they were influencing the content. The CDA provision got rid of that idea, at least in part.
