You want to remove this? So the runners of every forum on the internet will be responsible for content posted?
What part of that process is different from what Twitter is engaging in here?
Courts have departed from the most natural reading of the text by giving internet companies immunity for their own content. Section 230(c)(1) protects a company only when content is "provided by /another/ information content provider". Nowhere does this provision protect a company that is itself the information content provider.
And an information content provider is not just the primary author or creator, it is anyone "responsible, /in whole or in part/, for the creation of development" of the content. (words of justice Thomas)
They currently enjoy unlimited immunity in a way the spirit of the law does not allow. You can't enjoy tax breaks etc. of being a platform and then go and ban content that you don't agree with, but which is not harmful in the way the law lets you do. I.e. the law lets you remove illegal content, but if you are being treated as a platform, you can't just go and, oh, I don't know, not let the New York Post show a breaking story about Hunter Biden's laptop.
In the print world there is an in between: distributors, such as bookstores, newsstands, and libraries.
They do not become liable for false claims in books they sell. It is the authors or publishers of those books who are liable. If the bookstore itself produced libelous material, such as in a press release, they would be liable for that.
