>"It would be naive to think you can run an independent/secure cryptoapp based in the US." This seems to be a shot at WhatsApp and Signal, implying that they have loopholes that allow the FBI to snoop in. I'm not sure how true that is. This might be an attempt to deflect from the fact that Telegram uses a home-baked encryption protocol which might be insecure, while WhatsApp uses the OWS protocol.
Bingo. The CEO of Telegram likes to spread conspiracy theories that are good for business. In a recent tweet he claimed that Signal is "funded by the US government", [1] citing a ridiculous hit piece on OWS and Moxie.

Only the telegram server is closed source (for now), telegram client and protocol are open source.
