In which case, how in the world will anyone sane consent to "I didn't like this call - prove me wrong or give me $10"? (Yes, yes, make a law, I got that. Good luck getting that passed.)

This thread is not about a voluntary payment, and we don’t typically get to choose which laws we consent to. So I don’t know what you are asking.

Once the law is in effect, that is. First, it needs to be passed - and then, not shot down as unconstitutional. Moving the burden of proof to the operator (a third party! Not even one of the endpoints) sounds...very brave.
