The US should do similar to put an end to all of these competing charging formats and vertical markets. It's not like Tesla will lose out because they stand to profit regardless of which vehicle is charging at their stations.
You are Just Plain Wrong. The Supercharger network is a competitive advantage. Since no one else offers that, and no one else can charge at those points, as long as Tesla has it and nobody else does, it is a significant inducement to buy Tesla instead of something else. Thus, this is the time for Tesla to lobby against such a move. When other makers have similar networks, then Tesla will want to lobby for charge connector standardization, because that will force them to let Tesla customers use any charger. Once it's no longer a competitive advantage, then it becomes a drawback. Right up until then, it's a massive benefit and they would have to be total idiots unqualified to operate any business to change that part of their game plan.
