Dick,

Good question. Facebook Messenger is encrypted end-to-end. That means encryption happens on your device and is decrypted on your correspondent's device. No one can read the contents of your message while in transit, including Meta (who own Facebook). Many messaging systems similarly encrypt end-to-end. If I remember correctly, Facebook began encrypting Messenger end-to-end after their acquisition of Whatsapp which set the standard for consumer grade encryption. Signal and Terminal are encrypted also.

?

The upshot is that a VPN adds no value to security over Messenger, just overhead which slows things down.

To be clear, if you become a specific target for NSA, GCHQ, FIS, or other government intelligence agencies you have an entirely different set of problems. I can help you with those, but I'll need to be paid. *grin*
