This affects Signal too

An issue with Cloudflare allows an attacker to find which Cloudflare data center a messaging app used to cache an image, meaning an attacker can obtain the approximate location of Signal, Discord, Twitter/X, and likely other chat app users. In some cases an attacker only needs to send an image across the app, with the target not clicking it, to obtain their location.

Signal, an open-source encrypted messaging service, is widely used by journalists and activists for its privacy features. Internally, the app utilizes two CDNs for serving content: cdn.signal.org (powered by CloudFront) for profile avatars and cdn2.signal.org (powered by Cloudflare) for message attachments.

I wasn't trying to be short or condescending either. Just relaying what I know.

It is another layer of privacy in some cases. Could protect against poisoning of I'm not mistaken, but don't quote me.

I know for me, I prefer to self host things where I can so I can own as much of my own data as possible.
