A lawsuit filed against Facebook parent Meta Platforms Inc. is arguing that a federal law often used to shield internet companies from liability also allows people to use external tools to take control of their feed — even if that means shutting it off entirely.

Ethan Zuckerman's Unfollow Everything 2.0 extension lets people erase all their follows and start from scratch, but Meta has previously argued that such tools violate its terms.

Meta Platforms gets sued by First Amendment advocacy group that wants to allow an external tool that would let people control their content feeds.
