This is where the rubber hits the road. In the US you can walk around and sagely tell everyone how concerned you are and how you'd support thoughtful regulation safe in the knowledge that a few million on good lobbyists will completely derail any attempt at regulation. In the EU regulation will actually happen and the US CEOs still really haven't figured out a way of guiding this how they like. Threats like "If you do that we'll leave" just don't work on EU regulators, and US tech is a fantastically easy target for EU regulators.
