> "it’s no big secret that the NSA is listening in on the node/isp level" The NSA is doing deep packet inspection at every "node/isp" in the world? That's a pretty amazing claim. How are they managing that?
see https://en.wikipedia.org/wiki/XKeyscore for the sota from 20 years ago
If it required ~700 servers in ~150 locations (mostly US military bases and embassies) to surveil a small slice of internet and other traffic back then, how many would it require now? How many locations would those servers need to be situated? And how would NSA positions situated in embassies capture all of that Internet traffic in a foreign country without getting noticed?
Just think through the logistics of all of this and try to think of a way that any agency could accomplish it in 2026. And now think of all the people in the industry who would have to have at least some knowledge of it, or be able to discover a part of it.
Those are just some of the things one would need to explain and rationalize to even suggest that the NSA is doing what some of the people here are claiming.
