+							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
+							<a
+								href="https://www.fastcompany.com/90593066/whatsapp-facebook-privacy-ultimatum"
+								target="_blank"
+								>Facebook tracking</a
+							>. 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.
