Secure Messaging Apps Are Growing Faster in Corrupt Countries
Apptopia data determined secure messaging apps grew in MAU across the board in 2017, while “corrupt” countries grew even more.
Facebook Messenger and WhatsApp are the two most popular messaging apps in general. Privacy-focused encrypted alternatives like Signal and Telegram are both growing rapidly for those concerned about confidentiality or living in regimes where surveillance is all-encompassing.
It’s worth pointing out that Telegram has its origins in Russia and despite what people believe it is NOT open source. Its client-side code is open-source but the source code for recent versions is not always immediately published. Its server-side code is closed-source and proprietary.
Signal is developed by Open Whisper Systems. The clients are published as free and open-source software under the GPLv3 license. The server code is published under the AGPLv3 license.
