They can't immunize themselves from civil action relating to illegal acts or anything that violates public policy. Those are contracts. Contract law is controlling and the agreements are unconscionable, depending on which state you live in. FB shit all over Illinois biometric privacy law, they can't immunize themselves from civil suit in their ToS. They also can't get out of civil RICO (because let's face it, that's what big tech is…an ongoing criminal enterprise).
Appeal to Ninth Circuit. Ninth Circuit affirms district court. Petition for writ of certiorari, SCOTUS grants, vacates, and remands with an unsigned per curiam and Sotomayor dissent. That is my prediction.
