Unless Section 230 gets repealed, it's the exact opposite, actually.
I don't see how. Their actions are explicitly what are protected:
> Civil liability - No provider or user of an interactive computer service shall be held liable on account of
> (A)any action voluntarily taken in good faith to restrict access to or availability of material that the provider or user considers to be obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable, whether or not such material is constitutionally protected
Essentially nothing, which is why a few of the proposed bills to punish tech companies for removing content have tried to turn that into a clause with teeth.
It's important to remember that it's the first amendment that protects Twitter ability to filter anything it wants on its own platform, but it's the "material that the provider or user considers...otherwise objectionable" part of Section 230 that maintains the liability shield for other content that remains on their platform. That covers removal of essentially any content.
And hacked in what way? Didn't the repair shop owner take ownership of the computer after repeatedly asking for payment but not getting it? Didn't the owner give the hard drive first to FBI, then to a few media, and then to Giuliani?
As for fact checkers, Twitter didn't really fact check those media who give a report that says "anonymous source says", right? Twitter didn't really fact check that Jack Tapper contradicted himself now and in 2016 on exactly the same fine people hoax, right? Twitter didn't really fact check The Project 1619 that teaches us to hate America with a long list of inaccuracies (if not outright lies) or the critical race theory that claims that all white people are born racists or Asian people are complicit racists because they bought the values like working hard or being good at STEM, right? Or why isn't leaked tax records not "hacked"(FWIW, I'm only arguing the definition of "hacked", not whether it's good or bad to reveal tax record).
Oh wait, I guess I'm not exactly following the righteous narratives here, as all the morally superior mainstream media are doing. So this makes me a what? A bigot? A Nazi? A brown but really white supremacist? A racist?
