S. ____ (2024) 5 ALITO, J., concurring in judgment Content-moderation provisions. “Content moderation” is the gentle-sounding term used by internet platforms to denote actions they take purportedly to ensure that userprovided content complies with their terms of service and “community standards.” The Florida law eschews this neologism and instead uses the old-fashioned term “censorship.” To prevent platforms from discriminating against certain views or speakers, that law requires each regulated platform to enforce its “censorship . . . standards in a consistent manner among its users on the platform.” Fla. Stat. §501.2041(2)(b). The law defines “censorship” as any action taken to: “delete, regulate, restrict, edit, alter, [or] inhibit” users from posting their own content; “post an addendum to any content or material posted by a user”; or “inhibit the ability of a user to be viewable by or to interact with another user.” §501.2041(1)(b). To prevent platforms from attempting to evade this restriction by regularly modifying their practices, the law prohibits platforms from changing their censorship “rules, terms, and agreements . . . more than once every 30 days.” §501.2041(2)(c). And to give Floridians more control over how they view content on social-media websites, the law requires each platform to give its users the ability to “opt out” of its content-sorting “algorithms” and instead view posts sequentially or chronologically. §501.2041(2)(f ).6 Although some platforms still have employees who monitor and organize social-media feeds, for most platforms, “the incredible volume of content shared each day makes human review of each new post impossible.” Brief for Developers Alliance et al. as Amici Curiae 4. Consequently, platforms rely heavily on algorithms to organize and censor content. Ibid. And it is likely that they will increasingly —————— 6 As relevant here, an “algorithm” is a program that platforms use to automatically “censor” or “moderate” content that violates their terms or conditions, to organize the results of a search query, or to display posts in a feed.
