10 MOODY v. NETCHOICE, LLC Opinion of the Court that issue. In the lower courts, NetChoice and the States alike treated the laws as having certain heartland applications, and mostly confined their battle to that terrain. More specifically, the focus was on how the laws applied to the content-moderation practices that giant social-media platforms use on their best-known services to filter, alter, or label their users’ posts. Or more specifically still, the focus was on how the laws applied to Facebook’s News Feed and YouTube’s homepage. Reflecting the parties’ arguments, the Eleventh and Fifth Circuits also mostly confined their analysis in that way. See 34 F. 4th, at 1210, 1213 (considering “platforms like Facebook, Twitter, YouTube, and TikTok” and content moderation in “viewers’ feeds”); 49 F. 4th, at 445, 460, 478, 492 (considering platforms “such as Facebook, Twitter, and YouTube” and referencing users’ feeds); see also id., at 501 (Southwick, J., concurring in part and dissenting in part) (analyzing a curated feed).

They did not address the full range of activities the laws cover, and measure the constitutional against the unconstitutional applications. In short, they treated these cases more like as-applied claims than like facial ones. The first step in the proper facial analysis is to assess the state laws’ scope. What activities, by what actors, do the laws prohibit or otherwise regulate? The laws of course differ one from the other. But both, at least on their face, appear to apply beyond Facebook’s News Feed and its ilk. Members of this Court asked some of the relevant questions at oral argument. Starting with Facebook and the other giants: To what extent, if at all, do the laws affect their other services, like direct messaging or events management? See Tr. of Oral Arg. in No. 22–555, pp. 62–63; Tr. of Oral Arg. in No. 22–277, pp. 24–25; App. in No. 22–277, pp. 129, 159. And beyond those social-media entities, what
