WhatsApp cofounder wants you to delete Facebook

The context of this tweet is : Facbook is going through hell (well deserving) after the news came out on how Cambrige Analytica company used FB during elections time.
Does he have any skin in the game?
Brian Acton, WhatsApp cofounder left FB last year (he is now worth $6.5Bn, after WhatsApp acquisition). In fact, he has also invested $50mn into WhatsApp alternative, Signal.

Here is a question: In spite of knowing that Facebook is not just bad for your mental health, but is also a potential threat given that the company gives no damn to privacy (unless caught) – the mass users, do you think will delete Facebook?
Is there an alternative?
