> And that is completely consistent with precedent that the First Amendment actually protects people from censorship.
This is not the precedent! The first amendment absolutely allows citizens to engage in editorialization and "censorship".
The first amendment protects you from the government! And it gives me the right to assembly, including assembly with others in the form of a joint business venture! And if I assemble with others, very importantly: I don't lose my constitutional rights. Because even when I am assembled, I am protected from government overreach.
The Bill of Rights doesn't protect you from me, and it never has. The Bill of Rights does not protect you from censorship, and it never has. The Bill of Rights does precisely one thing: it protects you, and me, from the government and government overreach. And the government preventing me from speaking against you is government censorship of me.
Like, the ACLU, EFF, and Cato Institute all filed amicus briefs supporting NetChoice (previously when the even dumber part of this ruling was before the Supreme Court).
Edit in response to the below:
no, social media sites aren't common carriers, and you've already admitted that your whole fairness doctrine schtick is a stretch, since the internet's infrastructure isn't licensed by the government (and of course, it cannot be: I don't need a license to upload things!) Treating point-to-point social media, such as instant messaging, like a common carrier might make sense, but a reddit comment or a tweet don't resemble what common carriers carry or how common carriers work. They don't have a destination.
It's also, of course, important to note that there is no constitutional right to ship goods, so while it may be reasonable to regulate such industries, regulating a company whose product is speech is much more tenuous, so while the government can absolutely do common carrier things to a shipping company, it is enjoined, by the constitution, from making a speech company a common carrier.
Edit again:
Phone companies don't produce speech. I cannot hear what you say on the phone. I can see what you tweet. You might rephrase it as publishing vs. messaging. The regulations on a company whose product is publishing cannot be treated the same way as anything else (cue irrelevant arguing about a misunderstanding of section 230). Reddit and twitter and such allow me to publish what I say. T-mobile ships what I say. Common carrier regulations apply only to shipping companies, not publishing companies.
