France is banning ads for fossil fuels:
Édouard Leclerc, chairman of the Leclerc supermarket chain, said the ban on advertising would discourage the group from offering cut-price petrol. “If we have a reduction in the price of petrol, it’s a bit stupid if we can’t tell anyone,” he said.
It will also ban any new entrants into the market and thus fatten profit margins once again. That’s just what happens when you ban advertising – the aim of which is, as all should but don’t know, to move people from a competitor’s products to your own, not stimulate the original demand.
