I suppose it can't work in the USA, then. The American idea of freedom of speech is pretty unique, though, so it shouldn't be that much of a problem in most of the (free) world.
Ironically, the (electrical) engineer who had his free speech rights protected in the case was Swedish. And the (correct) argument he was ultimately allowed to make in Oregon triggered an update in international guidance on traffic light timing. So the rest of the (free) world will actually benefit regardless!
