It's a matter of herd mentality. The more the issue is raised, the more people will be willing to use services from other countries instead of US-based services, which means more non-US companies will gain prominence for certain services, which will encourage even more users to switch to them. As long as everyone thinks everything is fine if they keep using the same old US services they've always used, none of those steps will happen. Expect to get a push-back from users who prefer continuing to use US-based services so they can justify their own choice.
