Serverless architecture in many cases leaks the IP-address to the opposing party (without by-default anonymization via Tor). Cryptography is just math, nothing

Serverless architecture in many cases leaks the IP-address to the opposing party (without by-default anonymization via Tor). Cryptography is just math, nothing magical happens when p2p is applied, there's still a MITM risk, but there's no scalability issue in compromised IX-routers doing MITM against p2p system users, when compared to compromised Matrix servers doing MITM on mass scale. Less packet filtering but nation state adversaries don't exactly throw in the towel when they need to filter packets by protocol.
