Do you have a quote on eyeball hours? Fox at most gets 2-3 million viewers at prime time. Twitter has hundreds of millions of users and their reach exceeds even their membership, as Tweets often drive narrative on many other platforms.

You can read the order. Section 230 of the Communication Decency Act set out provisions protecting internet service providers from liability for obscene, lewd, etc content on the basis they are a neutral platform (like an email provider) and not an active arbiter and curator of content published on their page. The law clearly states it's protection for private blocking and screening of offensive material (lewd, lascivious, filthy, excessive violent, harassing, etc). Not for editorial protection. Not for arbitrary enforcement of TOS.
