“Fact-checkers have just been too politically biased and have destroyed more trust than they’ve created,” Zuckerberg declared in a video message. The tech giant plans to “dramatically reduce the amount of censorship” across Facebook, Instagram, and Threads, signaling a significant shift in how social media content will be managed.

After visiting President-elect Donald J. Trump in November, Mr. Zuckerberg decided to relax Meta’s speech policies. He asked a small team to carry out his goals within weeks. The repercussions are just beginning.

A new era is dawning at Meta. CEO Mark Zuckerberg announced on Tuesday that third-party fact-checking organizations would no longer have the power to suppress disfavored speech on Facebook—a major, positive step toward restoring free expression and robust debate on the platform.
