Yep, I'm familiar with Schneier's comments. I still find the whole thing funny though. For example, services like Viber seem to have 260 mil. active monthly users [1] which is a tad more than Telegram's 200 mil. on monthly basis, however, I don't hear people bashing Viber that much even though it practices security through obscurity [2]. Hats off to Telegram for at least publishing their stuff and I remain curious as to how it will all unfold in the future.
