Hey! Thanks for the mention! This video is based on the article we published a few months ago at the same time (quite literally) Privacy Guide published their video.
Original topic: What Is Browser Fingerprinting? (And How to Stop It!) - Announcements / Videos - Privacy Guides Community
Rtings article about it: VPN vs Browser Fingerprinting: A VPN Can’t Stop You From Being Tracked - General - Privacy Guides Community which includes the direct link.
tl;dr: Fingerprinting is very well explained by the Privacy Guides video. When visiting a webpage, your device sends information on its configuration to the website, so the website can send back the proper information to be rendered. Why is your device sending the info first? It was just built this way… and now we pay the price 
The amount of information your device sends create a unique “fingerprint” which can be tracked through your web browsing, and data brokers are well equipped to do that. They don’t know your name, but they can track your interest and sell that info to advertisers. In our article, we test how much you need to tamper with your fingerprint to “blend in” or be random enough not to be trackable, with the goal of better understanding what fingerprinting is and how powerful it is. Learning by experimenting!
I’m happy to discuss any questions that anyone might have!
