Seems like Facebook will be making plans to integrate Facebook Messenger, Instagram and Whatsapp. See this article from The Guardian:
The plan includes using end to end encryption for all messaging platforms. What’s the catch for an advertising-driven business? Is it Mark Zuckerberg trying to build Facebook’s image as protecting of privacy? Or is it a farce motivated by dark intents? Both of Whatsapp and Instagram founders have left Facebook in the past one or two years.
Your educated thoughts?
