Free speech is a very well defined concept, as done by literally hundreds of political science scholars. The fact that the US Constitution applies it only to the Government does not mean it cannot be discussed in a different context. For instance I would like new regulations to extend free speech outside the scope of the First Amendment. This is an extremely well defined politica stance.
You seem to agree that Twitter is NOT a common carrier, and then it must be treated as an editor. This would imply that they are responsible for the tweet they decide to publish.
These are exactly the far-reaching legal ramifications of free speech (outside Government) that I was mentioning.
What you are discussing in regards to free speech is again, by your admission, just a concept, not a law. All that matters is the law. Until its made law it has no bearing on the actions of a company. Section 230 of the Communications Decency Act means that whether you want to call them an editor or whatever, legally they are not responsible. The law is the law until it is changed, everything else is just an opinion.
I think we may have a failure to communicate. This entire thread is predicated on you stating that
"This is quite important from a legal standpoint, because since Twitter practices censorship of ideas they don’t like, they are no longer considered a common carrier. There are huge legal ramifications of this!" That's the entire central premise of the discussion. You are the one that brought up the legal aspect of it. Anyone can discuss anything in a conversation, it still does not change that its only a conversation, it does not affect the laws that govern how a company can be run.
Edit: Note - I am not blaming you for the communication breakdown, it seems that perhaps we were both coming at this from different sides and may have missed each others points. Either way, wish you all the best.
