What's worse, and what people gloss over, is that you have to sync your contacts to Facebook/Meta in order to use WhatsApp. That's a lot of very private information that tells them a lot about you. There is a reason why Facebook paid bajillions for WhatsApp and maintains it, even though the communication is encrypted and there are no ads — it's not out of the goodness of their noble hearts.

But try telling this to anyone and watch their eyes glaze over in a matter of seconds.
