Yeah that is kind of the point I wanted to get across. Fingerprinting isn't some major secret that big tech is using.. its a small tactic used by some companies that gets more attention than it really deserves. There is a section in part 2 specifically about fingerprinting under the subtitle "DENTIFYING A DEVICE WITHOUT AN ID". Browser fingerprinting is a single piece in creating an id graph. Fingerprinting would be 100% useless without a graph, unless you're doing it to individuals which would be NSA-level acting.
