OA to clear one of these items up a bit, it is well known that you cannot
have anonymity if the amount of stuff exchanged is observable.  This is a
problem called traffic analysis that has been a known vulnerability in tor
for many many years now.

There are ways to deter it but last I knew anything (which was some years
ago) the problem is still unsolved.

Doesn't it seem kind of impossible, "public anonymity"?  It is like wearing
a mask but being the only person in your community who buys fishfood.
People who see you buy fishfood know you are the guy with the pet fish,
whether you are masked or not.

This is a big topic because the tor project demonstrated trust when they
first released by disclosing that it was an unsolved problem in their
software in some areas.  To this day there are no mainstream systems that
address the problem of traffic analysis, and it takes a lot of
understanding of that problem to address it.
