The "volunteers will not be able to determine your location" claim is a little misleading

This line https://gitlab.torproject.org/tpo/web/snowflake/-/blob/8c8c301112a573a115d447c285168edf7e6ed6a4/content/landing-pages/04-faqs/contents.lr#L42, added in this MR !17 (merged).

The Snowflake proxies do know clients' IPs, and this is pretty much as close as you get to knowing someone's location on the internet. To support this: see tpo/anti-censorship/pluggable-transports/snowflake!482 (merged), which adds client country metrics to the proxy.

Instead of this, I'd say something along the lines of "will not be able to see what websites you're visiting: they'll only route your Tor traffic, which is anonymized".
