The wording implies that WhatsApp thinks that talking with your loved ones is an equally valuable experience as communicating with “businesses who matter to you”. I doubt many users are going to be convinced of that notion. No one joins a social media site or app because they simply cannot wait to connect with businesses and see more ads.
WhatsApp goes on to point out that they will share some user data with Facebook. It assures users that they have “rolled out end-to-end encryption”, and that user messages are encrypted by default.
WhatsApp also states that it won’t post or share your WhatsApp number with others, including on Facebook, and that it also won’t give your phone number to advertisers. Then, WhatsApp suggests that connecting your phone number to Facebook’s systems will enable Facebook to “offer better friend suggestions and show you more relevant ads”.
If you are using both WhatsApp and Facebook, and you want to opt-out of this new change, you can. WhatsApp has instructions on how to do that directly from the app.
