One feeds into the other strongly, though. The odds of an adversary de-anonymizing you go up the more activity the adversary can see. Also, we should look at your anonymity on a per-site/session basis, and if de-anonymization on one site breaks your anonymity on other sites, that is bad.

I fully agree that it is bad and a legitimate issue. As I said, "a very significant issue".
