Consider the difference between surveying your own population and engaging in espionage abroad. Obviously for your own citizenry there are concerns about you looking at their open habits or seeing if they visit the website of a law firm that has helped some evade taxes, or visited the website of a political party you don't like.

But if we are talking the citizens of other countries all the law enforcement users you might have just fall away and instead your only interest in that data would be for traditionally reasonable foreign intelligence grounds (or economic espionage which is a concern but not something that actually seems to be happening with Western countries). Now the us is a bit different because they are a global travel hub and take a very expensive view of their criminal laws to international actions. But generally your protection from a foreign country sitting on you is that they honestly, truly, just don't care about what you do online.
