That's hardly surprising. I mean browsers hand out willingly plenty of information that could be used for pretty accurate identifications. Just scrolling through my scores on amiunique[1], many of the parameters put me in the 0.01% category.
Using Mac OSX stock audio input and output devices is already supposedly "unique".
Having an Azerty keyboard supposedly puts you in the 0,04% category even though all French speakers have the same setting which means that 0,04% already represents +70M users. So far from "unique".
1. Visit the site 2. Delete your browser cookies 3. Refresh 4. Repeat the steps until you're less unique
The modern Web is a tracking system.
That's gonna take a lot of refreshing.....
