WhatsApp gives users an ultimatum: Share data with Facebook or stop using the app
The Facebook-owned messenger with 2 billion users revamps its privacy policy.

As "expected," Facebook really wants that contact data with all active (and probably primary) phone numbers. So.... what now? TBH, I'm not a fan of Whatsapp itself, but in my country, not using whatsapp is like not having a cellphone. It has ingrained in the society so much that even government institutions are using it. And imo it seems unlikely for majority of people to move to another platform.
On my Android, at least there's a "Not Now" option to "delay" the agreement, although I'm sure it's probably just a placebo.
