If I understand it correctly, there is nothing open about the server 
implemenation and infrastructure. So, I'm not sure how much the openness on 
the client side help here.

I also found this older article 
http://unhandledexpression.com/2013/12/17/telegram-stand-back-we-know-maths/
which I found quite interesting, especially the longer discussion in the 
comments between the author of the article and some guy from Telegram.

But I understand your arguments for the practical matters. Thanks again.

Regards,
Alexander
