Most likely the terms say that you agree to go through individual binding arbitration rather than a lawsuit which the courts have found to be legal and enforceable. It’s really shitty and has become corporations favorite weapon to use against people, particularly because the arbitration companies are usually fairly friendly towards whatever corporation is being challenged. Contractually mandated arbitration really needs to be invalidated. Arbitration is a fine alternative if both parties want to go that route but it should never be forced on someone, particularly because of some bullshit EULA.
