This relies on the assumption that traditional media isn't the source of disinformation and false claims, which at the best of times is far from true and even worse if you happen to live in a country where Murdoch media has a near monopoly. Then the question is does political advertising make the disinformation problem better or worse and I'm far less sure of that. It's easy to point to a few crazies but their influence is less certain and traditional media has always had plenty of crazy.
