Not that I disagree with the sentiment, but shouldn't you fix this at the source i.e. the government? If the American people don't want their government to spy on people .. vote for another government?

For any given US government, we’re basically always voting for people that we don’t trust very far, except to be marginally less of an asshole than the person we didn’t vote for.

The spying on citizens part is pretty entrenched, I don’t see any candidate running on a platform of not doing that.

Begging someone who does something bad (spying on their people in this case) to please stop doing bad things? That works?

Equating voting with begging is a serious false equivalency.

The government is made up of normal people. They get voted in by the rest of us. You can definitely change things if you dont like them, but you have to get enough other people to see it your way.

Who defines what is unethical? What is unethical for you might be ethical for others and vice versa.

The whole concept of ethics is about systematizing what's wrong and what's right. Obviously it's not a solved problem, but it's very far from just being a free-for-all.
