But a company operating an online gambling website in a foreign company is not doing business in the United States.

While that is true, it also seems true that even if a country like the US doesn't wish for political purposes to criminalize the actions of an American bettor but instead, whether legal or not in international law, to try to subject a foreign corporation to US jurisdiction, that there is an exception when countries have a reciprocal treaty as is the case with tax treaties. So if contrary to the spirit of the WTO countries were to mutually agree to subject their corporations to the jurisdiction of other signatory countries, then the onus could be placed on the company accepting/facilitating a wager by a foreign citizen at its site. Given the current events in various EU countries, this seems to be where all this might be heading de facto, if not de jure.
