Understood. You were clear about that.... but responding more below.

I agree that separate from end-to-end encryption, customized 'white
noise' can be useful mitigation but the specs of such a solution matter.
Ike had a story about Russian mitigation of German radio surveillance
during WWII. The Russians had numbers and relied on that for their
solution. *Everyone* spoke on the wire, about *everything*. The weather,
the latest radio broadcast performances, their kids' birthdays... and
since German radio surveillance relied upon individuals who could
understand Russian, the volume was beyond their capacity. The German
surveillance solution couldn't scale. Meanwhile, unencrypted high-value
communications continued in this large pool of noise.
Apparently this tactic continued well into the Cold War against US
The difference today is scaling. Digitized communications are easier to
collect in volume, and to store and process, without relying on
individuals to listen-in.
Digital surveillance can also more easily parse and discover anomalies
in the traffic. And then it can be correlated with cell phone traffic, etc.
Your local ISP surveillance device says: "I am watching lots of traffic,
and while I see the usual queries to the news www sites, I also see that
they are accessing Chase bank on the first of each month."
The point is white noise needs to be customized insofar as anomalies
can't be easily identified. It has to be lots of banks that are
accessed, including (you) the target's own banks, at regular sloppy
Of course, this is assuming a level of sophistication in terms of
surveillance processing... but who really knows today.
I would just run a Tor bridge at home to make your traffic sloppier, and
in the process you're also helping censored internet users around the
