Stick to messenger apps. It's tough, I know, because of network effects, but I managed to convert about 20 friends of mine to use Signal. I deliberately avoid Facebook Messenger and Whatsapp since they can be intercepted easily, and if you're caught making a joke about ISIS, the Whatsapp police can unencrypt your messages which kinda sucks.
Instant messages are more personal and you're not broadcasting your life to 5000 randos, who could potentially weaponize that data if they wanted (potential employer saw your meme about binge drinking & alcohol consumption? Too bad).
