A lawsuit was filed on behalf of Ethan Zuckerman, a professor at the University of Massachusetts Amherst, arguing that Section 230 of the Communications Decency Act protects the development of tools like his browser extension, Unfollow Everything 2.0.

The lawsuit seeks a declaration that Section 230 immunizes Zuckerman from civil liability or that the tool doesn't violate Meta's Terms of Service or relevant laws. The outcome is uncertain due to a novel interpretation of Section 230 and concerns about potential misuse of collected data.
