Stanford law professor Nathaniel Persily, who studies free speech and technology issues, said it’s also not clear whether demoting the reach of Trump’s dicey Facebook posts would blunt their impact because they are likely to gain attention elsewhere.

“So much of the power of his social media feeds is his ability to then set an agenda for other people, especially the legacy media,” Persily said. “It’s not clear that demotion has the same impact on someone like him as it would for the average person.”
