Cite as: 603 U. S. ____ (2024) 11 ALITO, J., concurring in judgment Platforms must allow users to appeal removal decisions through “an easily accessible complaint system;” resolve such appeals within 14 business days (unless an enumerated exception applies); and, if the appeal is successful, provide “the reason for the reversal.” §§120.101, 120.103(a)(2), (a)(3)(B)–(b), 120.104. Users may sue any platform that violates these provisions, as may the Texas attorney general. §143A.007(d). But unlike the Florida law, H.

Record in No. 1:21–CV–00840 (WD Tex.), Doc. 39, p. 23. But even if the platforms might have the right to use algorithms to censor their users’ speech, the State argued, the question of “what these algorithms are doing is a critical, and so far, unexplained, aspect of this case.” Id., at 24. This deficiency mattered, Texas contended, because the platforms could succeed on their facial challenge only by showing that “all algorithms used by the Platforms are for the purposes of expressing viewpoints of those Platforms.” Id., at 27. And because NetChoice had not even explained what its members’ algorithms did, much less whether they did so in an expressive way, Texas argued that NetChoice had not shown that “all applications of H.B. 20 are unconstitutional.” Ibid.; see also id., Doc. 53, at 13 (arguing that
