regarding the recent fingerprint discussions, I had look on fingerprint.com client-side javascript and found something I didn't know. Maybe you can comment. I did not find this in their public repo on github.
Its javascript seems to store a list of common forenames. Based on location "en-us", "en-gb", or russian, it picks a list of common forenames:
us: ["james", "mary", "john", "patricia", "robert", "jennifer", "michael", "linda", "william", "elizabeth", "david", "barbara", "richard", "susan", "joseph", "jessica", "thomas", "sarah", "charles", "karen", "christopher", "nancy", "daniel", "lisa", "matthew", "margaret", "anthony", "betty", "donald", "sandra"],
gb: ["oliver", "george", "noah", "arthur", "harry", "leo", "muhammad", "jack", "charlie", "oscar", "jacob", "henry", "thomas", "joshua", "william", "olivia", "amelia", "isla", "ava", "mia", "isabella", "sophia", "grace", "lily", "freya", "emily", "ivy", "ella", "rosie", "charlotte"],
ru: ["aleksandr", "sergej", "vladimir", "elena", "tatana", "andrej", "aleksej", "olga", "nikolaj", "natala", "anna", "ivan", "dmitrij", "irina", "maria", "mihail", "svetlana", "ekaterina", "evgenij", "viktor", "anastasia", "urij", "ulia", "valentin", "roman", "igor", "anatolij", "oleg", "pavel", "maksim"]

Researching some more it seems these .local domains are registered by apple devices on your local router. Depending on the phones name, it will register such a domain. You can ping it using the ping command, e.g. ping iphone.local
Is it now, that fingerprint.com is probing for these domains, and is in case of success, finding your device name and possibly your forname?
Sounds nasty to me. Any WEBRTC expert could comment?
