It’s becoming increasingly clear that for Facebook, there is no returning to its habits of the past.

Some of its most dramatic post-election changes, from algorithm tweaks to a strict crackdown on political misinformation, were supposed to be temporary — ” break-glass ” measures intended to prevent civil unrest as then-President Donald Trump spread false claims of a “rigged” election.

But the Jan. 6 insurrection, the rise in COVID vaccine misinformation and the persistent spread of malicious conspiracies — coupled with a new U.S. president and growing regulatory scrutiny around the world — have forced a reckoning at the social network.

“They don’t want to be the arbiters of free speech,” said Cliff Lampe, a professor studying social media platforms, moderation and misinformation at the University of Michigan. “But they have to be.”

For CEO Mark Zuckerberg, the past year has presented a series of humbling events that have picked away at his long-held assertion that Facebook is a worldwide force for good. In Facebook posts, public comments and discussions with employees, the CEO appears to be increasingly grappling with the dark side of the empire he created.

Take his approach to Trump, who until January enjoyed special treatment on Facebook and other social media platforms, despite spreading misinformation, promulgating hate and — what finally got him banned — inciting violence.

“Over the last several years, we have allowed President Trump to use our platform consistent with our own rules, at times removing content or labeling his posts when they violate our policies,” Zuckerberg wrote on his Facebook page on Jan. 7, explaining the company’s decision to suspend Trump. “We did this because we believe that the public has a right to the broadest possible access to political speech, even controversial speech.”

A day earlier, violent insurrectionists, egged on by Trump, descended on the U.S. Capitol in a deadly riot. While Facebook’s (and other tech companies’) move to ban a sitting president was unprecedented, many called it too little, too late.

It’s not yet clear if Facebook will banish the former president permanently, as Twitter has. The company batted that decision over to its quasi-independent Oversight Board — sort of a Supreme Court of Facebook enforcement — which is expected to rule on the matter in April. On Thursday, Zuckerberg, along with the CEOs of Twitter and Google, will testify before Congress about extremism and misinformation on their platforms.

Companies like Facebook are “creeping along towards firmer action,” said Jennifer Grygiel, a Syracuse University communications professor and an expert on social media, while noting a Trump ban alone doesn’t undo years of inaction.

Lampe said he doesn’t doubt that Facebook would like to return to its pre-2020, hands-off approach, but public pressure to crack down on extremism will likely win over. That’s because online extremism, fueled by social media — in the U.S. and around the world — is more and more tied to real-world violence.

The company is also facing a growing internal push from increasingly vocal employees, some of whom have quit publicly, staged walkouts and protests in the past year. Last summer, meanwhile, advertisers staged a boycott of Facebook’s business. And activists are finding growing support from lawmakers on the state, federal and global level.

Jessica Gonzalez, attorney at the racial justice group Free Press, recently joined Democratic Rep. Tony Cardenas and Latino activists in calling on Facebook to crack down on hate and misinformation targeted at Latinos in the United States. She said when she and other civil rights activists met with Zuckerberg last summer during an advertising boycott of the company, she reminded him of the 2019 massacre in El Paso, when a gunman targeting Mexicans killed 23 people.

“Facebook has a choice,” she said. It can be a “vector for hate and lies that harm people of color, Latinos, immigrants and other groups,” or on the right side of history.

“So far it has done a lot of talking,” Gonzalez said.

Facebook says it’s met with the organizations and shares their goal of stopping Spanish-language misinformation on its apps.

“We are taking aggressive steps to fight misinformation in Spanish and dozens of other languages, including by removing millions of pieces of COVID-19 and vaccine content,” the company said in a statement.

Though its moves have often been halting, the social media giant has worked to address some of the criticisms lobbed at it in recent years. Besides election misinformation, it has put restrictions on anti-vaccine propaganda, banned extremist groups such as QAnon, limited recommending other problematic groups to users and tries to promote authoritative information.
