They have fractured many other things with their regulations. Auto emissions, cancer warnings on everything.... I don't think they fear a fractured internet, if they even can understand that.
Yeah the cancer warnings seem to appear on just about everything but the CARB ratings for cars have probably saved a significant number of lives by dragging the rest of the country along for the ride with cleaner exhaust standards. Nothing to sneeze at.
I was hoping if they start enforcing it then more states will follow suit. Making laws and then selectively enforcing them when convenient is not a good idea. But you're right, that perhaps not enough time has passed yet and the worse is yet to come.
Possibly if some of those grim predictions start to come true they will take action.
