I imagine it’s somewhere between what both of you are saying.
I imagine “randomized” means a random common “fingerprint” (with parameters like user agent, language, etc) rather than just a unique set of randomized parameters (say, time zone in US but language set to Farsi which would be unique to an extent).



Sorry but that’s totally wrong.
The entire point is that if it’s unique it can be considered a fingerprint — in fact the entire reason it’s called “fingerprint” is that in theory it’s unique like a real fingerprint.
If it’s common then it’s unreliable as a fingerprint because it’s no longer unique. Therefore whether it’s unique or not is the entire point and relevant to the topic.
