No, the only one that knows your IP is your server. So your server knows your IP because you talked to it and the server knows the recipient servers IP because that's who you're sending to. And the recipient knows their servers IP but doesn't know your servers IP and doesn't know your IP. Now you can find the recipient servers IP by doing a ping obviously and they can find your servers IP that same way but they can't find your IP directly and you can't find their IP directly. Now, this may change for audio calls because that uses WebRTC, but I can't speak to that.
So why some nerds saying matrix as a metadata disaster?
Because encryption doesn't work for rooms over 50 people, so any room over that size is public by default. And most of the usage is the Matrix.org home server.
Even if I selfhost?
If you self-host, it's better, but it's still not great. The people would then know the IP address of your server that you were hosting it on, so you'd have to make sure it was a VPS and not done from home.
You could also put it behind a cloudflare proxy subdomain, right? That way it looks like the origin ip comes from cloudflare
Ugh, Yes, you could. But, Cloudflare.
What about using a normal, non-Cloudflare VPS for this?
