Cite as: 603 U. S. ____ (2024) 25 Opinion of the Court almost 9 million pieces of “bullying and harassment content.” App. in No. 22–555, at 80a. Similarly, YouTube deleted in one quarter more than 6 million videos violating its Guidelines. See id., at 116a. And among those are the removals the Texas law targets. What is more, this Court has already rightly declined to focus on the ratio of rejected to accepted content. Recall that in Hurley, the parade organizers welcomed pretty much everyone, excluding only those who expressed a message of gay pride. See supra, at 18. The Court held that the organizers’ “lenient” admissions policy—and their resulting failure to express a “particularized message”—did “not forfeit” their right to reject the few messages they found harmful or offensive. 515 U. S., at 569, 574. So too here, though the excluded viewpoints differ. That Facebook and YouTube convey a mass of messages does not license Texas to prohibit them from deleting posts with, say, “hate speech” based on “sexual orientation.” App. in No. 22–555, at 126a, 155a; see id., at 431a. It is as much an editorial choice to convey all speech except in select categories as to convey only speech within them. Similarly, the major social-media platforms do not lose their First Amendment protection just because no one will wrongly attribute to them the views in an individual post. Contra, 49 F. 4th, at 462 (arguing otherwise). For starters, users may well attribute to the platforms the messages that the posts convey in toto. Those messages—communicated by the feeds as a whole—derive largely from the platforms’ editorial decisions about which posts to remove, label, or demote. And because that is so, the platforms may indeed “own” the overall speech environment. In any event, this Court has never hinged a compiler’s First Amendment protection on the risk of misattribution. The Court did not think in Turner—and could not have thought in Tornillo or PG&E—that anyone would view the entity conveying the third-party speech at issue as endorsing its content.
