If you don’t do this, why do the new terms explicitly enable it, @WhatsApp / @Facebook? The logical answer is, you *will* be *able* to do it. 
It turns out messaging on @signalapp is “fast and reliable” without it having to send numbers to any third party. So if you have no need to collect numbers, take it out of the terms, and I’ll consider not leaving the service.
The clever use of the present, because the new terms are not in effect yet, is a form of lying. You are misleading the public. The new terms wouldn’t last a day under the GDPR. You need to stop this abusive nonsense.
We cannot consent to this, because our contacts HAVE NOT CONSENTED to having their details passed on by us to a third party. We ARE NOT AUTHORIZED. Don’t let the Facebook PR machine mix things up. This is not about the privacy of conversations on #WhatsApp.
