Browser fingerprinting is besides the point here. The whole reason they want to fingerprint you is to build up an advertising profile. FLoC cuts out the middleman by giving every single site you visit access to the proceeds of the cross-site tracking. It's like saying "There's too many cameras pointed at my house, so instead I'm going to start publically streaming my life 24/7".
