In January at the World Economic Forum, Nick Clegg, president of global affairs at Meta, called a nascent effort to detect artificially generated content “the most urgent task” facing the tech industry today. Now, Mr. Clegg has proposed a solution.

The major online platforms are breaking up with news. Some executives of the largest tech companies, like Adam Mosseri at Instagram, have said in no uncertain terms that hosting news on their sites can often be more trouble than it is worth because it generates polarized debates. Others, like Elon Musk, the owner of X, have expressed disdain for the mainstream press. Publishers seem resigned to the idea that traffic from the big tech companies will not return to what it once was.

Facebook has constructed a vast infrastructure to keep toxic material off its platform. At the center of it is Accenture, the blue-chip consulting firm. The two companies have rarely talked about their arrangement or even acknowledged that they work with each other, but their secretive relationship lies at the heart of an effort by the world’s largest social media company to distance itself from its content moderation practices.

Facebook moved to clamp down on any confusion about the November 2020 election on its service, rolling out a series of changes to limit voter misinformation and to prevent interference from President Donald Trump and other politicians. The social network, in one of its most sweeping sets of election actions, said it planned to bar any new political ads on its site in the week before Election Day. It said it would also strengthen measures against posts that try to dissuade people from voting.

Even with the global economy reeling from a pandemic-induced recession and dozens of businesses filing for bankruptcy, tech’s largest companies — still wildly profitable and flush with billions of dollars from years of corporate dominance — are deliberately laying the groundwork for a future where they will be bigger and more powerful than ever.

Twitter continued to add new fact-checking labels to hundreds of tweets, even as the Trump administration issued an executive order to curtail the legal protections that shield social media companies from liability for the content posted on their platforms. Twitter’s move escalated the confrontation between the company and President Donald Trump, who has fulminated over actions taken by his favorite social media service.

On Dec. 30, Andrew Bosworth, the head of Facebook’s virtual and augmented reality division, wrote on his internal Facebook page that, as a liberal, he found himself wanting to use the social network’s powerful platform against President Donald Trump. But citing the “Lord of the Rings” franchise and the philosopher John Rawls, Mr. Bosworth said that doing so would eventually backfire. “So what stays my hand?

Facebook has started to modify its behavior — in both pre-emptive and defensive ways — to deal with threats of regulation. Facebook has its eye particularly on the Federal Trade Commission, the agency that is now investigating it for anticompetitive practices.

The new reality for big tech companies: Scrutiny from regulators and lawmakers has become a constant. For the past few years, American regulators appeared to be lagging as authorities around the world have stepped up their actions to crimp the power of Facebook, Google, Amazon and Apple. The contrast was starkest with European officials, who have passed laws and imposed a series of large penalties against big tech companies. But in recent months, American lawmakers and regulators have also ramped up their activity.

Facebook CEO Mark Zuckerberg plans to integrate the social network’s messaging services — WhatsApp, Instagram and Facebook Messenger — asserting his control over the company’s sprawling divisions at a time when its business has been battered by scandals. The move requires thousands of Facebook employees to reconfigure how WhatsApp, Instagram and Facebook Messenger function at their most basic levels.
