The point is everybody is spying on everybody else. Every nation has spy agencies, and what they do is spying, it’s right there in the name. It’s just that the US operation is bigger and better funded, and has the biggest network of allies. This is not a shocking surprise to anyone in government anywhere, or anyone who knows almost anything at all about the history of intelligence work and espionage. The UK spied on the US throughout WW2. It’s how the world has always worked.

As for being a positive force in the world, that depends what they do with the information. It’s a different concern.
