Have used several browser fingerprinting services and have tried a few of the techniques myself, they're incredibly useful for fraud prevention when said fingerprint is reported against a central database alongside with the fraud that happened to _you_. The next time said fingerprint shows up at an eCommerce site, they'll be blocked off from purchasing or at least flagged for additional verification.
They're also just useful for super targeted ads.
