US Senator Sheldon Whitehouse on Friday said that he was moving to file a bipartisan bill to repeal of Section 230 of the Communications Decency Act.
Section 230 of the Communications Act of 1934, enacted as part of the Communications Decency Act of 1996, provides limited federal immunity to providers and users of interactive computer service, according to the US Congress website.
It generally provides immunity for online computer services with respect to third-party content generated by their users.
This provides immunity to platforms like Facebook, TikTok, X, ad Instagram from content posted by its users, essentially making free speech online.
The law has been applied to protect social media companies from lawsuits based on their decisions to transmit or take down user-generated content.
Experts argue that a repeal of Section 230 could kill free speech on the internet.
As the Legal Clarity website says
Without Section 230, many smaller platforms might be forced to shut down or never launch due to the overwhelming legal and financial burdens of defending against lawsuits or implementing extensive content moderation. This would create a significant barrier to entry for new companies, stifling innovation and competition in the online space. The result could be further consolidation of online power among a few large companies that can afford the increased legal and operational costs, limiting the diversity of online services available to users.
The EFF warns
The free and open internet as we know it couldn’t exist without Section 230.
