I have a bit of a different take on browser fingerprinting: I don't want to uniquely identify you as a person so I can serve you ads, or whatever. I want to identify your traffic when you're scraping my content from 2,000 different IP's and 1,000 different user accounts, I can block you or rate limit you without hurting anyone else.

Given the scale of scrapers these days (AI companies with VC money have no problem spinning up thousands of VMs running Chrome), fingerprinting at the browser level is the only realistic option.

(obligatory: my personal opinion, not necessarily my employer's)
