alt Hacker NewsA vulnerability is distinct from unintended behavior.
Unintended identification is less than ideal but frankly is just the nature of doing business and any number of niceties are lost by aggressively avoiding fingerprinting.
In software intentionally optimized to avoid any fingerprinting however it is a vulnerability.
The distinction being that fingerprinting in general is a less than ideal side effect that gives you a minor loss in privacy but in something like Tor Browser that fingerprinting can be life or death for a whistleblower, etc. It's the distinction between an annoyance and an execution.

In what way is collecting a record of a person's browsing history a "minor loss" of privacy. For many people, tracking everywhere they go online would easily expose the most sensitive personal information they have.
