Meta CEO Mark Zuckerberg announced a series of major changes to the company’s moderation policies and practices Tuesday, citing a shifting political and social landscape and a desire to embrace free speech.

Zuckerberg said that Meta will end its fact-checking program with trusted partners and replace it with a community-driven system similar to X’s Community Notes.

The company is also making changes to its content moderation policies around political topics and undoing changes that reduced the amount of political content in user feeds, Zuckerberg said.

The changes will affect Facebook and Instagram, two of the largest social media platforms in the world, each boasting billions of users, as well as Threads.
