@rysiek This is downplaying it way too much for my taste. Let me explain:
The rough location information is usually only available to servers. Now, even though I prefer zero trust, I would argue that trusting a messenger's server to not give away my rough location is way more reasonable than trusting the person that uploaded the data I'm downloading from the server.
**But in this case, the person that uploaded the data can extract the location I'm downloading it from.** This is big. It takes metadata to a whole different level.
I also want to quickly respond to the arguments:
That very rough radius could actually a pretty big deal in less populated areas.
The second argument is whataboutism. (And there are definitely apps that are not affected.)
Kinda agree with the third one though.

If I were #Signal, I would turn off the caching mechanism for now and urge #Cloudflare to rethink their statement. The privacy protection mechanisms are clearly lacking. Cloudflares position is simply not acceptable.
