So it's hard to "trust" in a single direction when the actions that cause distrust are so, so bald-faced. Every conspiracy-sounding theory surrounding surveillance has turned out to be true. And all that worry about being caught has had a net-zero effect. Maybe Let's Encrypt was at least partially a result, but that's about it. So why worry now? Turns out secret courts are just about guaranteed to green-light whatever the hell the NSA wants, so people finding out didn't really turn out as badly as they were worried about.
So "trust us" is about impossible anymore. I don't know if the relationship can be healed, to be honest. Obama was the ideal of our best shot, but that ship sailed like, day 2.
The #1 goal of the Neoliberal elite class is to crush the will of people like you. If you've already given up then you might as well be dead to them; they don't even need to spy on you at that point! If, on the other hand, you're out in public and organizing in large numbers then what can they do? You can force them to engage with the issues on your terms.
If people are upset, enough to effect change, they only have to start showing up. Find the game, learn the game, play the game.
Technology alone cannot solve political problems. The technology can be banned.
Technology can, however, raise the difficulty for sub-components of a government that are wanting to push the limits and do things outside the boundaries of the politically agreed upon systems. Encryption can't stop the NSA if it has widespread political support because the encryption can be banned. But right now intelligence agencies are absolutely hurting, because what they're doing is highly controversial and blocking them with encryption is not at illegal. If the political debate is won, even if it's just a partial win, then they're forced back inside their box for a long time to come.
I'm glad there are people fighting the political fights too, though I can't imagine where they get the patience. I certainly have nothing to offer in that arena.
I take your point about the NSA, but it doesn't appear that political action will stop them either, because they are happy to ignore political constraints (and lie to Congress about it, for example) and simply do whatever their technological capabilities allow them to.
A war on encryption would be much easier to enforce than a war on drugs because there are such fewer sources, and there's not a big market for its use.
Trust no one
With this sort of attitude you might as well give up on life. Society doesn't work without trust between people.
