This is an One time viewable/self destructing Message which might be pushed every now and then, until you tap Agree..
Followed by that is the expected one:
We're Not Changing the privacy of your personal conversations, WhatsApp provides clickable link to view Whats being changed, and when you tap/click the onescreen link, you will see the same things, the data will be end to end encrypted, no one can view your WhatsApp chats or calls neither WhatsApp nor anyone, blah blah texts.
One big highlight in this new updated policy is, WhatsApp Says, it will label facebook tools. And Interacting with this business is purely Optional.
Who won't monetize an App, which has morethan 1 billion active users every day? Of course, everyone will, in the world where we have to some cost to almost everything.!
But WhatsApp takes a wrong route of targeted ads.! Which means, you will see the ads' which you need to see..!
So, What will happen if i don't agree?
Simple, you will stop receiving messages and gradually to nil. So, its upto you to continue using WhatsApp :)
