WASHINGTON (NEWSnet/AP) — The Supreme Court cast doubt Monday on state laws that could affect how Facebook, TikTok, X, YouTube and other social media platforms regulate user content.

The cases are among several this term in which the justices could set standards for free speech in the digital age.

In nearly four hours of arguments, several justices questioned aspects of laws adopted by Republican-dominated legislatures and signed by Republican governors in Florida and Texas in 2021. But they seemed wary of a broad ruling, with Justice Amy Coney Barrett warning of “land mines” she and her colleagues need to avoid in resolving the two cases.

While the details vary, both laws aimed to address conservative complaints that the social media companies were liberal-leaning and censored users based on their viewpoints, especially on the political right.

Differences on the court Wednesday emerged over how to think about the platforms — as akin to newspapers that have broad free-speech protections, or telephone companies, known as common carriers that are susceptible to broader regulation.

Chief Justice John Roberts suggested he was in the former camp, saying early in the session, “And I wonder, since we’re talking about the First Amendment, whether our first concern should be with the state regulating what we have called the modern public square?”

Justices Samuel Alito and Clarence Thomas appeared most ready to embrace arguments made by lawyers for the states. Thomas raised the idea that the companies are iseeking constitutional protection for “censoring other speech.”

Alito complained about the term “content moderation” that the sites employ to keep material off their platforms.

“Is it anything more than a euphemism for censorship?” he asked, later musing that term struck him as Orwellian.

But Justice Brett Kavanaugh, seemingly more favorable to the companies, took issue with calling the actions of private companies censorship, a term he said should be reserved for restrictions imposed by the government.

“When I think of Orwellian, I think of the state, not the private sector, not private individuals,” Kavanaugh said.

The precise contours of rulings in the two cases were not clear after arguments, although it seemed likely the court would not let the laws take effect. The justices posed questions about how the laws might affect businesses that are not the primary targets of the laws, including e-commerce sites like Uber and Etsy and email and messaging services.

The cases are among several the justices have grappled with over the past year involving social media platforms.

Next month, the court will hear an appeal from Louisiana, Missouri and other parties accusing administration officials of pressuring social media companies to silence conservative points of view.

Two more cases awaiting decision concern whether public officials can block critics from commenting on their social media accounts.
