Major law firms are jumping into the Federal Trade Commission’s antitrust lawsuit against Meta to represent technology companies seeking to have their corporate secrets shielded from Facebook’s in-house counsel.

The companies, which include social media platforms Twitter, Reddit, LinkedIn, Pinterest and Snap along with the online dating company Match Group and the software giant Oracle, said they either turned over information to the FTC as part of its investigation into Meta or have been subpoenaed by Meta in discovery.
