Cite as: 603 U. S. ____ (2024) 11 Opinion of the Court do the laws have to say, if anything, about how an email provider like Gmail filters incoming messages, how an online marketplace like Etsy displays customer reviews, how a payment service like Venmo manages friends’ financial exchanges, or how a ride-sharing service like Uber runs? See Tr. of Oral Arg. in No. 22–277, at 74–79, 95–98; see also id., at 153 (Solicitor General) (“I have some sympathy [for the Court] here. In preparation for this argument, I’ve been working with my team to say, does this even cover direct messaging? Does this even cover Gmail?”). Those are examples only. The online world is variegated and complex, encompassing an ever-growing number of apps, services, functionalities, and methods for communication and connection. Each might (or might not) have to change because of the provisions, as to either content moderation or individualized explanation, in Florida’s or Texas’s law. Before a court can do anything else with these facial challenges, it must address that set of issues—in short, must “determine what [the law] covers.” Hansen, 599 U. S., at 770. The next order of business is to decide which of the laws’ applications violate the First Amendment, and to measure them against the rest. For the content-moderation provisions, that means asking, as to every covered platform or function, whether there is an intrusion on protected editorial discretion. See infra, at 13–19. And for the individualized-explanation provisions, it means asking, again as to each thing covered, whether the required disclosures unduly burden expression. See Zauderer, 471 U. S., at 651. Even on a preliminary record, it is not hard to see how the answers might differ as between regulation of Facebook’s News Feed (considered in the courts below) and, say, its direct messaging service (not so considered). Curating a feed and transmitting direct messages, one might think, involve different levels of editorial choice, so that the one creates an expressive product and the other does not.
