Whatsapp breaks two promises after being acquired by Farcebook's:
1. whatsapp gets facebook directed ads,
2. whatsapp gets further integrated into facebook.
Click read and do not accept the user license, but one has to do that (not applied as per default) within 30 days.
You also have to set to "do not share" under settings.
Now facebook algoritms have acces to your every whatsapp message,
despite of the Privacy Shield Treaty, as big commerce will anyway do as they please,
what else services besides targeted ads services will be able to read into your every whatsapp message? NSA, FBI?
Do not share with Whatsapp what you do not wanna share with others. Your data is what you pay for free services, and your privacy then stops to exist and what you share may come to bite you later.
