An Attack on Telegram
"Some viable alternatives I can recommend are Threema or TextSecure."The problem with Threema and TextSecure is that it's hard to convince my friends to use them because- Threema is not free and does not have desktop/web clients, and multi-device setup is not supported afaik
- TextSecure is not really multi-platformThe only popular, multiplatform messengers at the moment are Whatsapp, FB Messenger, Viber/Line and Telegram. Whatsapp doesn't have a desktop client, Messenger requires a Facebook Login, Telegram and Whatsapp does not have voice chat and I hate Viber's design -> so I keep using Telegram for messaging and Skype for voice.The network effects can be very nicely observed in messenger usages. In my home country almost everyone uses Viber, but in other countries I have worked (W-EU) almost everyone uses Whatsapp. In Germany people seem to know Telegram, in other places nobody heard about it.
