Trustworthiness is not an absolute thing. I trust my German government pretty far though, because I know I and my people can eventually hold them responsible for most things. The U.S. government, in most things, I also -mostly- trust, maybe not that far, but a lot farther than Russia or China.

And yes, I'd much rather have the NSA spy on me, than Russia and China. And that often is the choice when choosing technologies.
