CIA is not stupid enough to break into a guarded data center in Switzerland or one of the less America friendly EU countries.

Big tech services are less private than you think but almost every provider who cares about privacy is safer than you expect. Most of the people who work there are committed to their mission, and if they ever get a gag order someone will leak it in no time because they know exactly how to do it without exposing their identity.
