The cool thing is that they make you go into forced arbitration rather than through the legal system.
The cooler thing is that if a substantial amount of the 216M TV owners tried to arbitrate across the country/world, they'd cave so fast. Arbitration is cheaper than an individual law suit, but much much more expensive than a class-action.
