I have thought about trying to run a VPN server on my EC2 web server for my friends in Iran but not sure if regular VPN protocols are even allowed through. I don't think they know what Tor is much less how to set it up with a custom bridge. They seem to be using some kind of proxy/bridge for Telegram, but didn't know the technical English vocab to tell me exactly what it was.
Ironically, I once talked to someone very pro-regime on HelloTalk and asked them why they were using Telegram if it was blocked/illegal there, since they would defend the regime on anything else you asked them about. They claimed to believe that it was blocked because of US sanctions and denied that the government blocked any websites. Is this a narrative they are pushing on state media there?
