WhatsApp claims the changes will make the experience better for its users.
However, WhatsApp is keen to reiterate that users’ encrypted messages will remain private and the California-based firm won’t post, sell, share, or give your phone number to advertisers.
“By coordinating more with Facebook, we’ll be able to do things like track basic metrics about how often people use our services and better fight spam on WhatsApp,” the company explained on its blog.
