It has kept Microsoft from sharing its EU data with American agencies so far.. and considering Microsoft has been under the microscope (haha) since it's EU antitrust suit I don't think they could pass the data without some serious ramifications. As far as ProtonMail goes.. well they certainly could force the support employees somehow, but if that ever gets out there would again be serious ramifications. Plus, why do you think the US Enterprise IT services/hardware industry took a serious hit when all the NSA leaks happened? What do you think will happen if it gets out that the US is even forcing foreign companies to obey to US law? I'm not counting on the NSA to behave - I'm counting on America as a whole to be greedy and put business above enforcement.
