Cite as: 603 U. S. ____ (2024) 33 ALITO, J., concurring in judgment For Zauderer purposes, a law is “unduly burdensome” if it threatens to “chil[l] protected commercial speech.” Ibid. Here, NetChoice claims that these disclosures have that effect and lead platforms to “conclude that the safe course is to . . . not exercis[e] editorial discretion at all” rather than explain why they remove “millions of posts per day.” Brief for Respondents in No. 22–277, at 39–40 (internal quotation marks omitted). Our unanimous agreement regarding NetChoice’s failure to show that a sufficient number of its members engage in constitutionally protected expression prevents us from accepting NetChoice’s argument regarding these provisions. In the lower courts, NetChoice did not even try to show how these disclosure provisions chill each platform’s speech. Instead, NetChoice merely identified one subset of one platform’s content that would be affected by these laws: billions of nonconforming comments that YouTube removes each year. 49 F. 4th, at 487; see also Brief for Appellees in No. 21–12355 (CA11), p. 13. But if YouTube uses automated processes to flag and remove these comments, it is not clear why having to disclose the bases of those processes would chill YouTube’s speech. And even if having to explain each removal decision would unduly burden YouTube’s First Amendment rights, the same does not necessarily follow with regard to all of NetChoice’s members. NetChoice’s failure to make this broader showing is especially problematic since NetChoice does not dispute the States’ assertion that many platforms already provide a notice-and-appeal process for their removal decisions. In fact, some have even advocated for such disclosure requirements.
