The problem is that the US has for a very long time pretty much unchecked global power. All our free-speech, what is it good for, if it cannot effect change? Look where Snowden is. Even the captain mentioned in the article pretty much told people what he did, and so is The New York Times now, but if people don't bat an eye what's the point? Heck the whole NSA spying thing was leaked something like 5 years before Snowden, and nobody cared.
I think most American's won't really care about what our government is doing to others thousands of miles away so long as we can buy our iPhones, watch our movies, and browse our TikTok.
I think the only practical thing that can be done is to encourage competition from America's equally-sized rivals (pretty much just China at the moment). That being said, these other countries are often not saints themselves (looking at you China), but competition is really the only thing that can check the abuse from any single party. While there are smaller "better" countries they are still within America's sphere of influence and even if you move there and avoid contributing to US taxes, you still end up contributing to that ecosystem that essentially powers the American system (most US allies participated in the war in the middle east).
