I doubt think that's true at all. In most representative democracies (UK here) we just don't have the ability to vote on such fine-grained legislation. If you asked the person in the street "should companies be held to absolutely strict truth in advertising for quantitative claims", once you explained what it meant (!), I'd warrant the vast majority would agree, yes they should.
It's anti-democratic, and anti-capitalist to allow misinformation on products. Markets can't optimise if you allow misinformation.
