Not really sure how it works, I think it's based on browser language? Devs would know better.
But where is it leaking this to? What's the "major" concern?
Nostr clients are using your IP geolocation and/or checking your browser language – to automaticly show notes from other users who also share the same country as you.
This leaks information about the user location/country, and is major concern for privacy reasons.
Not sure if every client is doing this, #Snort #Iris are clearly doing it, especially noticeable when not logged in. When logged in there is no option to disable this behavoiour and seems to be enabled by default.

For example, if I'm in France or have my browser set to French, when I post something, even if it's in english, it'll show up on the main feeds of French users, even if they don't follow me directly.
Users might not know my exact IP address, but based on this "feature" they can know my location/language because the client it self is leaked it.
I think it would only post to french timeline if your browser is set to french. I'm in Japan and my browser is all English and I don't show up in Japanese timelines (I don't think) - unless people are following me from japan which some are.
