For messaging, self host or use a matrix instance outside of UK jurisdiction so that Big Tech cannot secretly weaken encryption without your knowledge.
Thus standing out from the crowd by using a traditional VPN makes you suspicious. Routing all your traffic through a single IP is also indicative of an obfuscated VPN.
My current setup: Tun2socksn -> local host socks5 proxy -> multiple outbound xray instances routed through different CDNs (or not) to make traffic look “normal”
Which outbound a specific IP takes is randomized and cached for 1 hour.
