There are so many ways to fingerprint a browser and new ones are introduced and discovered all the time. The best protection against fingerprinting isn't to try to be the same as everyone else and pray that you've somehow accounted for every possibility, but to always present as a different browser. It can only take changing a single data point to look like a new browser/device, although you still have other things like your IP address which can associate fingerprints with each other. A VPN can give you a new IP every day, or every few hours which can help.

This is interesting, sure, but you would need more data to create a better identifier.

I’m on an iPhone, which isn’t an uncommon device using Brave which is just WebKit because of iOS restrictions. So there would be lot of iPhones that would just end up being with basically the same identifier.

Youtube uses a lot of fingerprinting based recommendations. It's always good to see it going south whenever you alter most of the used properties.

How do you determine if the guy who brought your paid subscription is using the same account on multiple devices then?

Ok, thanks for the list of information to destroy
