Telegram's ability to enable this type of activity is just about to get a big boost. It just announced plans to launch its own cryptocurrency in a multi-billion dollar ICO (initial coin offering -- it's akin to an IPO but without investment banks, the SEC, and stock markets).
This ICO will not only fund its ongoing and future operations, it will richly reward the founders -- which has always been a disincentive for development in this space. Further, an integrated cryptocurrency will make it a much more dynamic social network for open source insurgencies.
