“For example, if someone is using Facebook in abusive fashion, sending malicious links to users and we are able to identify that account also on WhatsApp, we can disable that account and its services rather than just on Facebook,”
The new update will also positively affect Facebook’s Custom Audience ad platform for businesses, by displaying more “relevant ads” by pulling data for different phone numbers associated with the two services.
“For example, if you sign up to your local flower shop’s mailing list using the same mobile phone number that you use for your WhatsApp account, and they decide to advertise on Facebook, you may see their ads on Facebook,” the WhatsApp rep explained.
How To Opt out
Wisely, Facebook has provided a way to opt out of all this if it hadn’t done so, it could have faced an exodus from WhatsApp, with users electing to join one of its many rivals, such as Telegram or Viber.
When accepting the terms and conditions in the updated app, you have to click “read,” rather than blindly accepting them. There you will see a control at the bottom of the screen inviting you to “uncheck” the box giving your permission. If you inadvertently agree to the new terms, you’ll have 30 days to change your mind and toggle the settings in your account.
