I do not believe there is such thing as privacy from such organizations. If they want you bad enough, they will get you. Don't have a reason? They'll make one.
Do you remember the "Heartbleed" exploit in SSL many years ago? There were allegations that the NSA knew about and used that exploit for many years before the public ever knew about. However, that is not exactly an easy statement to confirm nor deny.
While I was writing this message , I was roaming out side in the street , my street isn't developed, so there is a lot of empty space 2 sides of my house.
I saw a peacock flying & sitting in front of my house. It was so majestic. It's wings when they fly , the sound they produce is such majestic that it touches your mind.
The solution isn't a cabin in the woods , the solution is living in such remote area like I live , seriously I am not that far away from the main town , but still this place is so nice I just realized but development would come , and houses would get built. Then there would be no more peacocks flying in.
I really get what you are feeling. But I believe that getting away from dystopian technology is far more easier by degoogling with grapheneos or getting a dumb phone like me & linux with sandboxing each applications ,I do think that we can get far away , like they would need to find a bug in such things like qemu , pledge , flatpak etc. though I think they might already have found a bug in some version and like you said, are waiting.
The only solution I can find is to read the source code of these sandboxing applications on linux and to never update it / it should be such that doesn't require updates , a completely minimal sandboxing solution.
How can we imagine they use their powers for good , when the president has handed things over to oligarchy who want maximum profits. What benefit do they get from using their power for good ? None. I am sure that they are using the power of both good and evil.
And with the recent Debacle of Snooper's Law apple e2ee backdoor.
Let me tell you something. A company is asked for a backdoor and they are forced to not tell anybody about it.
The only reason why it was leaked was because of whistleblower. And so , who knows if they have already signed such thing with the NSA or UK already but for their mac's and other devices
