No, due to browsers leaking data and state actors controlling tor end points.
They still know know someone out there is doing something, and can build ad profiles and threat profiles on them, they just can't link those profiles to you easily: that is anonymity.
Privacy would be inability to build useful profiles.
Interesting. But if someone could remain anonymous, even with a profile being created for that "anonymous entity" and there is nothing tying that anonymous profile back to a real person, that would still seem to be private to me. If the anonymous profile could be connected to a real person, that would seem to be neither anonymous, nor private.
