Neither you nor I can say definitively what the law is until it's been testedin court and really until the Supreme Court weighs in and that just hasn't happened yet. At least I'm saying "this is my opinion (and, as an aside, I'm not alone in that opinion as I've pointed out). Condescendingly posting a "here's why you're wrong" link doesn't make you smart. Or informed. Or correct. Just confidently wrong.

Even in this post you contradict yourself. If S230 doesn't grant more rights, why does it matter? If it makes it easier, then it's giving you something, just like anti-SLAPP statutes give you something (and matter).

Also, this isn't a First Amendment issue. Nobody is questioning whether a platform can publish their own content or somebody else's. The issue is liability for what it is expressed. Publishing your own content comes under a strict liability [1] standard. Section 230 establishes that publishing third-party content does not, which again contradicts the point that that "230 does not give platforms any new rights".

Wouldn't you agree there's a difference between being able to post defamatory or false statements with or without liability?
