Except Valve, for their Steam service. But that's only because someone realized that you could Zerg rush them with arbitration claims, whose fees they were obliged to pay (since their ToS forced users into it). Their only option that wouldn't be massively disruptive financially, in that case, would be to agree to a settlement with the arb representatives. So, now, you're only allowed to sue Valve, in a specific court of their choosing.
