+ I'm a big fan of free and open source software. This
+ is especially important with messenger apps where
+ user privacy is very important. Signal uses the same
+ end-to-end encryption protocol (Signal Protocol) as
+ WhatsApp, but without the
+ Facebook tracking. This means it is incredibly difficult to
+ intercept and decode messages sent through Signal.
+ Since Signal is an independent nonprofit, they are
+ not tied to any major tech company and they cannot
+ be acquired by one in the future. They are entirely
+ funded by donations and grants. If you are looking
+ to move away from messenger services like WhatsApp
+ and Facebook Messenger, Signal is the best option.
