Not only Telegram still working here, but it was a great experience yesterday.
Imagine the following: a manager in a supermarket explaining how to setup a proxy to a customer so that she (a woman in her 60s) could use their bot again.
Or a woman with a kid who is asking what the are going to do: "It's okay, we'll ask dad and he's going to do proxy-something".
Similar things long going on in Crimea for the same reasons established by the other side (whatsapp and viber are blocked by whatsapp and viber owners correspondingly). When I was there, everyone seemed to have a vpn on their phones and getting it installed was none of a problem.
Smarter people are better!
